Hi, The Thread.sleep() tests were not really deterministic. This fixes that by explicitly waiting for the helper thread to sleep and never using "zero sleeptime". The downside is that the tests now takes between 10 and 12 seconds because of the explicit sleep() statements. The upside is that the results are now deterministic. 2005-10-12 Mark Wielaard * gnu/testlet/java/lang/Thread/sleep.java: Explicitly wait for helper thread to start sleeping. Add extra debug info.
