[PATCH] bump mirrorlist processes

We're running into a problem where we're seeing 30 requests/second for
the mirrorlists, but we only have 6 processes available for apache to
send those to.

This bumps up the number of processes, from 6 to 30, and cuts the
number of threads from 25 to 1 (it's a single-threaded requestor app,
and there's the python GIL still to deal with).

We may need to do more on the mirrorlist-server.py process to handle
the load (it fork()s on every connection), but this is a start...
