While testing meta-command pgbench only scripts, I noticed that there is
an infinite loop in threadRun, which means that other tasks such as
reporting progress do not get a chance.
The attached patch breaks this loop by always returning at the end of a
script.
On "pgbench -T 3 -P 1 -f noop.sql", before this patch, the progress is not
shown, after it is.
