[Python-checkins] CVS: python/dist/src/Python traceback.c,2.24,2.25

[Guido van Rossum]

Update of /projects/cvsroot/python/dist/src/Python
In directory eric:/home/guido/hp/mal/py-patched/Python

Modified Files:
	traceback.c 
Log Message:
Christian Tismer's "trashcan" patch:

Added wrapping macros to dictobject.c, listobject.c, tupleobject.c,
frameobject.c, traceback.c that safely prevends core dumps 
on stack overflow. Macros and functions in object.c, object.h.
The method is an "elevator destructor" that turns cascading
deletes into tail recursive behavior when some limit is hit.
