Apache spawns multiple processes, not threads. (that changes a bit with 
Apache 2, but lets ignore that for the moment.) Zope uses threads 
instead.

The Linux kernel, before version 2.6 had relatively primitive thread 
support, and built threads out of multiple processes with some memory 
sharing. Linux 2.6 has more advanced thread support that supports the 
pthread standard. One side effect of real pthreads is that all threads 
are really within the same process.

If you use the command and options "ps auxm", you will see displayed 
the threads within the process.
