Test to highlight the bug

This test starts a group of "load" threads (CPU count * 4) whose purpose is
only to burden the CPU - theoretically making the crucial race condition more
likely.
It then starts 2 threads that wait and wake (all) on the same address. The only
difference is that the second thread skips the first wait.
The test fails if any wait takes longer than 10 seconds to be notified.  Purer
versions of this test mean bigger wait times. The failure occurs quite quickly
on my 2 core 4 thread processor, although if you have a high thread to core
ratio, the test may not fail due to insufficient load.
