hi,

please remember that 'nice' is not a magical fix for programs that use too much
CPU.  if a program uses a lot of CPU, it should be reniced; but that doesn't
mean that you can use as much CPU as you like as long as you renice it.

if you write a tool that uses 50% CPU constantly, you are using 6.25% of the
total available CPU on the Toolserver for yourself.  if everyone did this, we
could only support 16 users before running out of CPU.  we have a lot more than
16 users, so please be considerate, and monitor your CPU use.

	- river.
