What if you have several databases?  Does the maximum number of connections 
need to be the mximum number of httpd processes TIMES the number of 
databases?  ouch.

If so, does Linux's way of dealing with multiple processes using the same 
code mean that even if you do have hundreds of simultaneous DB connections, 
it won't necessarily use an exorbitant amount of memory?

I'm wondering if I'm making that mistake.  What rights should it have?  Seems 
like it needs to be able to do pretty much anything with tables -- insert, 
update, delete, etc.
