The reason we decided to launch multiple process is so that we wouldn't
compound the blocking issue that occurs when multiple requests come in at
the same time. I'd love to have only one server handle all this. Or even
better have it behave like apache where I can launch 10 servers and have
it serve information from 100 DBs.

I want them in seperate DBs. The DB is where most of the concurentcey
issues are, correct?

What files report information under /proc? If you receive any of these 
scripts please pass them on to me. I think we will create a few beta sites
for anybody interested on the list  and then monitor their usage.
