description:
kre@ notified me that the kernel/t_threadpool "rapid" test was occasionally
tripping a KASSERT() failure in the i386-qemu test rig.  It turns out this
is due to "rapid" simply being a buggy test that makes assumptions that
aren't always true, especially on slower / uniprocesor hardware.  So, the
right thing to do is just remove the test.
