Have each of them check for a completion file when they complete
successfully.  If it exists remove it and start progc.  If not create a
completion file and exit (there is a possible race condition here).

Both should be started from the same script, of course, which should handle
the completion file, errors and cleanup.  No need to modify the programs.
