NOTE:
It's NOT a good idea to
nice
a
foreground job (
12.1
)
.
If the system gets busy, your terminal could "freeze" waiting to get enough
CPU time to do something.
You may not even be able to
kill (
38.9
)
a
nice
'd job on a very busy system because the
CPU may never give the process enough CPU time to recognize the signal
waiting for it!
And, of course, don't
nice
an interactive program like a text editor
unless you like to wait...
:-)
