 I've reproduced this on the following setup:
 
 6.3-RELEASE SMP i386 kernel
 libthr
 2 cores
 
 However, the lost wakeup is on the main thread. The last
 broadcast wakeup from the worker threads gets lost and
 the process deadlocks.
 
 So far the test program has not provoked the lost
 wakeup using libpthread on 6.3.
 
 Initial 7.0 (amd64 libthr) testing has not provoked the
 issue yet either.
