BTW, mine similar problem completely disappeared after I switched to
SMP kernel and turned on hyperthreading on my workstation Pentium IV 3GHz.
I am able to run FPS games while doing 1 (and, most of the time, even 2)
compilations/configure run) in parallel. The scheduler used is ULE,
I believe there is something wrong with UP; I did not investigated what.
