the test2 scenario fails due to the calculated timeout of a receive being greater than the imposed quasi realtime upper bound.

Test2 starting
checkTime: got = 10699 start = 4000 end = 4000
----------System.err:(13/669)----------
java.lang.RuntimeException: checkTime failed: got 10699, expected between 4000 and 4000
