[Zope3-dev] zope.component dependency on zope.testing

[Baiju M]

Hi,
   zope.testing is a dependency for zope.component because
zope.testing.cleanup.addCleanUp  method is used in 
zope.component.globalregistry
This code only works when running tests ?
Can we can make zope.testing dependency optional like this:

  Index: src/zope/component/globalregistry.py
