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.
