nice, with no arguments, will give you your current nice level. ps and top
will diplay the nice level (or sometimes priority) of processes. Also,
BSD::Resource, found on CPAN, has a method for retrieving a process's
priority. I'm fairly certain there are more ways of getting the information.

Ok, the test was seperate. Have you tried running strace on the program to
see where it's sleeping? Are you certain it's sleeping, or is it possible
it's blocking on a read or write?

This code doesn't work for me, though it may be because of a difference in
uptime output. Have you verified Load() returns the value you expect?
Also, &Load has slightly different meaning from Load(), due to the &. It
doesn't look like it will effect you here, but you should check perldoc
perlsub for the difference between them.
