[mod_python] mpm-worker and mod_python

Hi,

I had mod_python 3.3.1 running on Apache 2.2.4 with mpm-prefork (on  
Ubuntu 6.10 x86_64). mod_python wasn't caching modules so I  
recompiled apache with mpm-worker instead. Now mod_python is caching  
modules but apache is taking up 100% of system resources. Is it  
possible to cache modules with Apache using mpm-prefork? Has anybody  
else seen all system resources get taken up by using mod_python and  
mpm-worker?

thanks,
-Andres
