Update of /cvs-repository/Zope2/lib/python/AccessControl
In directory korak.digicool.com:/projects/sites/devzope/lib/python/AccessControl

Modified Files:
	User.py 
Log Message:
Added careful caching to getRolesInContext, which is an expensive op 
that requires climbing the entire aq chain on every call (and it gets
called a *lot*). A little investigation revealed that it is called 
over and over for the same objects during a request for complex pages, 
so a cache was added that can cut the work down to about 10% of its 
current level.
