Actually it doesn't look that bad, just that the test code isn't waiting long
enough for all the once-<n> threads to run; they are running later on, but by
then it's stopped counting. Try increasing the delay immediately before the
testOk(doneCount==...) line.
This is the place where I really wanted a broadcast epicsEvent that would
start all the waiting threads at once, to test that the once really can't be
executed in parallel.
