In directory usw-pr-cvs1:/tmp/cvs-serv14857/Modules

Modified Files:
Tag: release22-maint
gcmodule.c
Log Message:
Backport to 2.2.1:

This is Neil's fix for SF bug 535905 (Evil Trashcan and GC interaction).

The fix makes it possible to call PyObject_GC_UnTrack() more than once
on the same object, and then move the PyObject_GC_UnTrack() call to
*before* the trashcan code is invoked.

BUGFIX CANDIDATE!
