Update of /cvs-repository/Zope/lib/python/Products/PageTemplates
In directory cvs.zope.org:/tmp/cvs-serv4233

Modified Files:
	TALES.py 
Log Message:
Fixed a memory leak in TALES.  If an exception occurs in a repeat block, a
cycle is left behind that includes a SafeMapping, and SafeMappings are not
aware of GC, therefore the cycle can't be collected.  Iterator is also in the
cycle, however, and it does not need a strong reference to the Context object,
since the Context refers to the Iterator.  So Iterators now refer to Context
through a weak reference.
