Thanks for keeping the investigation going!

For what it's worth this is what I have been experimenting with:
http://cr.openjdk.java.net/~dfuchs/experiment-8219585/experiment.00/

It's only a POC and obviously need more cleaning.
Maybe some of the arbitrary timeouts in the test could be scaled
in accordance to timeout-factor (I think there's an adjustTimeout(long)
function somewhere in the test libs that does that).

I ran it 50 times in our test system - and it passed on all platforms,
so there's yet hope :-)

hope this helps,
