[Zope-dev] Re: [Zope] ANNOUNCE: Zope 2.4.0 alpha 1 released

>     - New restricted execution architecture

A note about this for those who have run afoul of restrictions on
builtins such as 'list', 'map', and 'range' in Scripts and DTML Python
expressions:

In the new architecture, there are (by default) no attempts to protect
the system against excessive CPU or memory utilization.  Unless you
explicitly turn on such limits (not implemented yet), anyone who has
permission to write DTML or Scripts in your Zope can accidentally or
deliberately consume all available resources with infinite loops or huge
data structures.  Realistically, they could before, they just had to be
slightly more creative.

Cheers,
