changes in sbcl-1.0.30 relative to sbcl-1.0.29:
  * minor incompatible change: SB-THREAD:JOIN-THREAD-ERROR-THREAD and
    SB-THREAD:INTERRUPT-THREAD-ERROR-THREAD have been deprecated in favor
    of SB-THREAD:THREAD-ERROR-THREAD.
  * new contrib module: SB-QUEUE provides thread-safe lockless FIFO queues.
  * new feature: docstrings for local and anonymous functions are no longer
    discarded. (thanks to Leslie Polzer)
  * new feature: SB-THREAD:SYMBOL-VALUE-IN-THREAD provides access to symbol
    values in other threads.
  * new feature: SB-INTROSPECT:ALLOCATION-INFORMATION provides information
    about object allocation.
  * optimization: division of a real float by a complex float is implemented
    with a specialised code sequence.
  * optimization: MAKE-INSTANCE with non-constant class-argument but constant
    keywords is an order of magnitude faster.
  * optimization: MAKE-INSTANCE with constant keyword arguments is x2-4 faster
    in the presence of :AROUND or non-standard primary INITIALIZE-INSTANCE
    methods, and similarly for non-standard metaclass classes as long as there
    are no methods additional on MAKE-INSTANCE.
  * optimization: more efficient type-checks for FIXNUMs when the value
    is known to be a signed word on x86 and x86-64.
  * optimization: compiler now optimizes (EXPT -1 INTEGER), (EXPT -1.0 INTEGER),
    and (EXPT -1.0d0 INTEGER) into an ODDP test. (thanks to Stas Boukarev and
    Paul Khuong)
  * optimization: compiler is smarter about delegating argument type checks to
    callees.
  * optimization: several character functions are now compiled somewhat more
    efficiently. (reported by Lynn Quam)
  * optimization: the compiler now derives simple types for LOAD-VALUE-FORMs.
  * improvement: less unsafe constant folding in floating point arithmetic,
    especially for mixed complex/real -float operations.
  * optimization: constant double and single floats are stored in native
    unboxed format on x86[-64].
  * optimization: smarter code for arithmetic operations with constant floats,
    complex floats, or integers on x86[-64].
  * optimization: smarter code for conjugate/multiplication of float complexes
    and abs/negate of floats on x86-64.
  * optimization: more efficient complex float and real float operations on
    x86-64.
  * improvement: complex float division is slightly more stable.
  * improvement: DESCRIBE output has been reworked to be easier to read and
    contains more pertinent information.
  * improvement: failure to provide requested stack allocation compiler notes
    provided in all cases (requested stack allocation not happening without a
    note being issued is now considered a bug.)
  * bug fix: SB-POSIX exports the documented types and functions
    FILE-DESCRIPTOR and FILENAME, and also the corresponding -DESCRIPTOR
    types. (reported by "abhi")
  * bug fix: on 64 bit platforms FILL worked incorrectly on arrays with
    upgraded element type (COMPLEX SINGLE-FLOAT), regression from 1.0.28.55.
    (thanks to Paul Khuong)
  * bug fix: looping around HANDLER-CASE could silently consume stack space
    on each iteration. (reported by "foobar")
  * bug fix: better error signalling when calls to functions seeking elements
    from lists (eg. ADJOIN) are compiled with both :TEST and :TEST-NOT.
    (reported by Tobias Rittweiler)
  * bug fix: regressions in DIRECTORY from 1.0.28.61: pattern matching of
    directory components now works as it used to. (various prolems reported by
    Michael Becker, Gabriel Dos Reis, Cyrus Harmon, and Harald Hanche-Olsen)
  * bug fix: :PTY option in RUN-PROGRAM was broken with stream arguments.
    (reported by Elliot Slaughter, thanks to Stas Boukarev)
  * bug fix: bogus undefined variable warnings from fopcompiled references to
    global variables. (thanks to Lars Rune Nøstdal)
  * bug fix: foreign function names should now appear in backtraces on
    FC6 as well. (reported by Tomasz Skutnik and Tobias Rautenkranz)
  * bug fix: SETF compiler macro documentation strings are not discarded
    anymore.
  * bug fix: GENTEMP is now unaffected by pretty printer dispatch table.
    (thanks to Alex Plotnick)
  * bug fix: SLEEP accepts large integer arguments, truncating them to
    SIGNED-WORD on the assumption that sleeping for 68 years is sufficient
    for anyone. (reported by Leslie Polzer, thanks to Stas Boukarev)
  * bug fix: compiler notes for expensive slot type checks could be emitted
    at runtime MAKE-INSTANCE calls. (reported by Samium Gromoff)
