> Shutdownhook that halts JVM is causing test runs to fail

> When all the unit tests actually pass, surefire still reports that there was 
> an error in the fork. This is because it doesn't like the fact that a forked 
> JVM called system.exit() or system.halt(). We have a shutdown hook in 
> BaseTest which does that. Such failed runs happen more frequently on the  
> 4.x-HBase-0.98 branch. And sometimes on the master and 1.1 branch. 
> I know the code was added because we were seeing test runs hang. Since we 
> changed a lot of tests since then, I would like to remove that hook and see 
> if it helps.
