[Zope] Threading, dtml and performance?!

[Chris McDonough]

This "hogging" behavior doesn't show up on a Linux 2.4.2 kernel, Zope
2.3.3 system we have here.  I can browse the site normally while the
DTML method runs.

I don't have a Solaris machine to test this on; can anyone else
confirm the behavior on Solaris?
