Verify that "ldmadmin pqactHUP" signals *all* pqact(1) processes #121

According to a NOAA/NWS person, "ldmadmin pqactHUP" signals all pqact(1) processes but only one process logs a message and that's for the default pqact(1) configuration-file.

An enhancement to the LDM would be for ldmadmin(1) to send a SIGHUP to the LDM process group to ensure that all pqact(1) processes received it. It would require, however, that all other processes in the process group ignore the signal. This would take considerable editing. Child processes of pqact(1), however, would be safe because they're made part of a different process group.

Either vet the Perl code in ldmadmin(1) or do the above.
