As distributed, file "uucico" must be setuid-root.  It increases
its priority (nice -20) and then execs "uucico." at this higher
priority.

This procedure is only advisable for those sites which intend to make
frequent use of UUCP while the system is experiencing a heavy CPU
load.  Running uucico "niced-up" does allow it to requisition enough
CPU resources to prevent protocol time-outs; unfortunately it will also
cause the performance of any other tasks to be seriously degraded.

If your site does not use uucp; you can stop reading.  Its priority
is moot if you won't be running it.

If you use uucp moderately, for moderately sized files; or if your
machine load is not typically heavy, you should not run uucico
at an increased priority.  Type:
	mv uucico uucico.hipri
	mv uucico. uucico
which will de-install the uucico priority modification.
