Sufficiently for whom?  It took me 20 minutes of massaging just to get
it to build under vc7.1 (where I have good debugging tools).  Then when
I tested it against a Python debug build the vc7.1 runtime found a
problem with corrupted dynamic memory.

Please reduce your problem to a *simple* test case with as few classes
and functions as possible.  Take out any threading-related stuff.  There
should be one .cpp file and one .py file.  Ideally, you'd pass me a
Jamfile, but I can produce one myself if neccessary.

Thanks,
