vrban: p_crasher2 still does not correctly simulate parallel queries.  A
condition broadcast may allow all the threads to start at the broadcast
time at the earliest, but as I stated before, if the entire set of commands
can occur in a single context switch, then it is still only serializing the
queries.  You need to ensure that each step is completed in tandem (and at
various offsets) using condition variables before you have a valid test of
multiple queries existing in various states in parallel.

pabelanger: the issue is still in triage state, as a cause has not been
determined.
