Getting better but still not perfect.  It survived a couple of -j128
buildworlds with another six -j16 buildworlds running in parallel.

But it still has the same issue pho's stress test - a thr1 process is
blocked in urdlck.  The improvement is that there's only one stuck
process and it took 7¼ hrs at INCARNATIONS=150 instead of 1-2 hours.
(And it runs out of witness locks).
