Subject: [PATCH] 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.
