mempools conversions, more ..

ok. This makes the aio stat request pool use a memPool. I think I'm going
to end up being flogging boy on converting things to mempools here. :-)

I'll go in and commit my comm.c mempool additions since I've been running
them here without any mishaps.

*puts on mempool hat and wonders how much ram squid will stop chewing ..*
