Hello, Guennadi.

I've been looking at the code and am scratching my head about what
happens after timeout.  If test timed out (tmo == 0), it prints out
error message and continues to the next iteration of the test loop,
which will reinitialize the on-stack completion.  This essentially
makes the previous test run's callback_param pointer dangling.  The
completion needs to be either detached from the callback or waited
upon even if it timed out.  Am I missing something?

Thanks.
