New Revision: 39361
URL: http://svn.boost.org/trac/boost/changeset/39361
Log:
A minor optimization to eliminate two OS calls (one
to times, one to kill). Now all expired processes
are killed in one place. If the select command
times out, I set each processes start_time to zero
to ensure it is picked up as an expired process.
