[Zope] Threading, dtml and performance?!

[Chris McDonough]

The output of the DTML method isn't important, but if you ran it and it 
took a while (> 5 seconds or so), but then at the same time it was 
running, you visited a page in the mgmt interface and that operation 
took .83 seconds, that's the number that's important.. that lets us know 
that MP Linux systems aren't "freezing" like Solaris systems.  However, 
if you ran this method, and you couldn't do anything on the system until 
it finished, there would be a problem.
