Summary: ZODB cores with 2.2.1 CVS

Initial Comment:
As summary.  May happen with other extension packages;
this is the first I've tried.

Obviously 2.2.1 can't go out until we figure out why
this is happening.  Currently backing out changes and
working by binary chop, but help appreciated!

Verification also appreciated.

Does this patch fix the problem?  I've been meaning to look 
at it since I noticed it yesterday, but haven't had time.

The ZODB test-suite?

I got the impression "roughly anything at all".

I could be more helpful :) but I don't have a pymalloc-ed
binary around anymore and it's home time here.

Agree it's likely to be exactly the sort of thing I fixed in
the _cursesmodule.c a whiles back PyMem_Del vs PyObject_Del.

Good grief, sf is having a bad day today!

--with-pymalloc problems shouldn't hold up anything.  
obmalloc is still experimental, and it appears hard for 
large C extensions *not* to screw up when it's enabled 
(thanks to widespread misues of Python's mem-mgmt API).

It would help if you attached an example that provokes ZODB 
failure.

I'll leave this open, just in case.

That would seem to be it, yes.

Should probably try to work out why, but I'm not sure it's
going to be our problem.

Or maybe it's --with-pymalloc that does it?
