Hello!

I'm experiencing serious slowdown when rc5des runs on my PPro200.
I understand that this thing would eat up all the CPU it can, but
I did not expect it to noticeable affect the time it takes elm to
spawn `more' with a mail message. After I used idprio, the time
went from 3-4 seconds to about one -- still long. man also takes
noticably longer to come up. "!uname -a" from `vi' just took 2
seconds!

It seems, the programs run quick, but take much longer to start.
Any ideas? The system is
