Update of /cvsroot/python/python/dist/src/Lib/test
In directory sc8-pr-cvs1:/tmp/cvs-serv22191/Lib/test

Modified Files:
	test_cpickle.py 
Log Message:
SF bug 690622: test_cpickle overflows stack on MacOS9.
test_nonrecursive_deep():  Reduced nesting depth to 60.

Not a bugfix candidate.  2.3 increased the number of stack frames
needed to pickle a list (in order to get implement the "list
batching" unpickling memory optimization new in 2.3).
