[Zope3-checkins] CVS: Zope3/src/zope/component/tests - test_service.py:1.4

[Jim Fulton]

Update of /cvs-repository/Zope3/src/zope/component/tests
In directory cvs.zope.org:/tmp/cvs-serv29575/src/zope/component/tests

Modified Files:
	test_service.py 
Log Message:
Made global service managers picklable as global objects.

Added GlobalService base class for creating pickleable global
services. Global services are pickled by reducing them to (now
picklable) global service managers and service named.
