Update of /cvsroot/python/python/dist/src/Lib/test
In directory sc8-pr-cvs1:/tmp/cvs-serv28869/Lib/test

Modified Files:
	test_gc.py 
Log Message:
New tests identical to boom and boom2, except using new-style classes.
These never failed in 2.3, and the tests confirm it.  They still blow up
in the 2.2 branch, despite that all the gc-vs-__del__ fixes from 2.3
have been backported (and this is expected -- 2.2 needs more work than
2.3 needed).
