Jon,

By coincidence, I just typed up answers to some related frequently
asked questions here:

   http://ms.gis.umn.edu/docs/faq/thread_safety

The same FAQ with some extra editorializing is on my news page:

It's not your imagination, we are trading performance for thread
safety, and you may very well expect certain components of MapServer to
be slower.

cheers,
Sean
