bugfix: Diskd has a loop that puts Squid to sleep for small amounts of

time when the queues size reach a threshhold.  The time-to-sleep is
supposed to double each time through the loop, but struct timeval delay
was initialized inside the loop, rather than outside, which meant it
always slept for 1 microsecond.
