/* Return how often to spawn a uuxqt process.  This is either a
   positive number representing the number of execution files to be
   received between spawns, or a special code.  When using
   TAYLOR_CONFIG, this is from the ``run-uuxqt'' command in config
   (the default is UUCONF_RUNUUXQT_ONCE, for compatibility).
   Otherwise, we return UUCONF_RUNUUXQT_PERCALL for HDB_CONFIG and 10
   for V2_CONFIG, to emulate traditional HDB and V2 emulations.  */
