Here are other candidates to try turning off:

>            Reporter: stack
> Looking at recent builds of 1.2, I see a few of the runs finishing with kills and notice
that a JVM exited without reporting back state. Running the hanging test finder, I can see
at least that in one case that the balancer tests seem to be outstanding; looking in test
output, seems to be still going on.... A few others are reported as hung but they look like
they have just started running and are just killed by surefire.
> This issue is about trying to disable a few of the problematics like balancer tests to
see if our overall stability improves. If so, I can concentrate on stabilizing these few tests.
Else will just undo the experiment and put the tests back on line.
