Commit Message

--rate mode: fix latency stats skew on low rates

Worker threads used sleep() in the bounded rate mode to avoid CPU
hogging when polling on the event queue. The problem was that sleep()
calls increased time spent by events in the queue, which is counted
towards event latency to avoid the coordinated omission problem. The
lower the rate, the bigger impact on latency was observed.

The fix is replacing sleep()s with a condition variable which is now
used to put worker into an idle wait when the queue is empty. The event
generation thread now uses pthread_cond_signal() after each generated
event to wake up an idle worker thread. Which somewhat increases
sysbench CPU consumption, especially for high rates.
