Here's the cute bit - either (a) we can have a socket redirector process
sitting at the front of the X squids, or (b) we can modify the ipf/ipfw/
ipchains/whatever code to do load-balancing redirection.

Depends how it is implemented. See, if we use aio, we can schedule reads
of the file from multiple processes and have the reads block whilst the
object is being written. Squid can't do that now due to how the storage
manager is written but I don't imagine it'd be that hard.
