sb-threads on NetBSD, errors

Hi all,

I'm attempting to get sb-threads working on NetBSD and I'm running
into some errors when running tests. SBCL compiles without concern
and I'm not sure if threading will work completely without the tests
fully succeeding. Here is where it fails:

// Running /usr/pkgsrc/lang/sbcl/work/sbcl-2.4.7/tests/gethash-concurrency.pure.lisp in COMPILE evaluator mode
::: SKIPPED-BROKEN (HASH-TABLE :UNSYNCHRONIZED) Test broken on this platform
::: Running (HASH-TABLE :SYNCHRONIZED)
::: Success (HASH-TABLE :SYNCHRONIZED)

::: Success (HASH-TABLE :PARALLEL-READERS-EQ-TABLE)
::: Running (HASH-TABLE :PARALLEL-READERS-EQL-TABLE)
[1]   Trace/BPT trap (core dumped) (set -u; if [ ${#} -gt 0 ]; then "${SBCL_RUNTI...
test failed, expected 104 return code, got 133

I've tried looking to see what that error number means but no dice.

If I skip the test, it fails later with the same error doing
something related to threads.

Anyone able to point me in the right direction here?
