TODO: (JSB) This blocks forever on Linux (not Windows) because

This must be caused by starvation because
replacing the test with Thread.sleep(n)
gives the same result if n is large enough (2000

Resolve this in some way, perhaps by switching to
non-blocking io (and then remember to remove the next line).
