Re: pgbnech: allow to cancel queries during benchmark

I forgot, about the test:

I think that it should be integrated in the existing 
"001_pgbench_with_server.pl" script, because a TAP script is pretty 
expensive as it creates a cluster, starts it… before running the test.

I'm surprise that IPC::Run does not give any access to the process number. 
Anyway, its object interface seems to allow sending signal:

 	$h->signal("...")

So the code could be simplified to use that after a small delay.
