To avoid race conditions, the Apache timeout should be _larger_ than
Squid timeout. If Apache only talks to Squid, then it does not hurt to
set the Apache timeout to twice the value of Squid timeout. It is the
_smaller_ timeout that will effectively determine the number of idle
persistent connections between the two points in this case.
