... and note that we always experience a little noise in the Process_, Thread_
and Throw_ testcases, which I believe to reflect an underlying bug in Cygwin's
threading/synchronisation code somewhere, as we get similar noise in the
libstdc++ mutex_weaktoshared tests and there's a hang in one of the libgomp
testcases too.  Whatever it is, it's always been there and is unaffected by
this change.
