kernel/current/tests/klock failure

[Hans Rosenfeld <rosenfeld at grumpf dot hope-2000 dot org>]

While running the klock test, I get the following error message:
FAIL:<bad result from cyg_mbox[_timed]_get()> Line: 254, File: /usr/local/share/ecos/packages/kernel/current/tests/klock.c

What happens here is that while the first thread is waiting in
cyg_mbox_get() for a message the second thread puts a message in the
mailbox but immediately gets it back itself because it is not waiting
for the first thread to change its state.

Putting a message in the mailbox is scheduling the first thread to run,
but is not immediately causing a switch into it. I guess that is exactly
as it is supposed to be.

I attached a simple patch to fix this by inserting a wait for the state
change of the first thread.
