It's fine with me.  We maybe just need to remove the C extension in
it... someone (you?) provided a pure python implementation of what it
does that probably runs just as fast.

I wouldn't be apt include the Scheduler product in the core.  I think it
may be a tad too complicated.

The Event product is likely superseded by the Zope 3 event system
included in Five.
