Attached an attempt at improving things.
I've put 2 barriers: one so that all threads are up, one when all
connections are setup and the bench is ready to go.
I've done a blind attempt at implementing the barrier stuff on windows.
I've changed the performance calculations depending on -C or not. Ramp-up
effects are smoothed.
I've merged all time-related stuff (time_t, instr_time, int64) to use a
unique type (pg_time_usec_t) and set of functions/macros, which simplifies
the code somehow.
I've tried to do some variable renaming to distinguish timestamps and
intervals.
This is work in progress.
