[Zope-Perl] Benefits of Zope multithreading

[Gisle Aas]

I am trying to evaluate what the current single lock that protects the
perl interpreter means to Zope's performance when running PerlMethods.

But, I don't really understand what the multithreading buys us in the
first place.  What is it that actually works better given the Zope is
multithreaded?  Is there any design documents I can look at?

The single python lock seems to mean that Zope can't really manage to
utilize multiple CPUs anyway and the Medusa framework should make sure
Zope can deal with multiple slow clients even without threads.
