Could it be that unix-like shell (which I haven't looked at) is actually
dumb enough to sit in a polling loop waiting for you to enter something?
That would explain the symptom, since the foreground task gets priority.
(And the background would get a share of the CPU when the foreground does
something else, such as any disk I/O). 

Just speculation... you could check it out by running one of the CPU 
monitor programs and see if it shows 100%.
