[Zope-dev] Untrusted developers

[Chris McDonough]

This would be a fairly difficult thing to do internal to Zope given the
numerous ways people can write infinite loops.

You might want to take a look at the Autolance product at
http://www.zope.org/Members/mcdonc/Products/AutoLance.  It wasn't
written for this scenario but might work anyway.
