The patch is ready to go, with a few changes to make error reporting
consistent (both internally and with the rest of the Python API).  I
would have checked it in yesterday, but my ISP is having some kind of
routing trouble and I can't reach the Python CVS server at
Sourceforge.  Sheesh!  You'll know when the problem is fixed :-).
