Fix a couple bugs and remove the IGNORE variable:
 - select can be interrupted and return EINTR so we need to loop around it
   while it does so rather than treating it as a fatal error.
 - all process creations are matched with a wait() so having a SIGCHLD
   handler that performs a wait(-1) is pointless and racy.  We tend to
   loose the race over half the time and as a result were reporting
   successful processes as failed.

Add a couple features:
 - Skip commented lines in the host specification.
 - Allow '-' as an alias for stdin in the host file specification.
