Summary: Improve exception pickling support

Initial Comment:
Due to various issues with how pickle works and new-style classes, pickling exception objects has been somewhat unreliable since Python 2.5.  See comments in patch #1692335 for more detail.  Attached is a patch that seems to improve pickling exceptions to support various different types of subclasses.

It has some limitations (exceptions that use __slots__, doesn't fully support SyntaxError, UnicodeError, SystemExit, or WindowsError).  However, it is an improvement for my situation.

Eric, could you comment on the current version of the other patch?  Does
that work for you?  Is that sufficient?  If not, how are they different? 
Should they both be applied, in part or in whole?
