Andreas Gudian commented on SUREFIRE-946:
-----------------------------------------
Where do you see {{ProcessHook}} acquiring a lock? I think terminating the
forked VM is not the problem.
I think the (remaining) problem is if the forked VM terminates _without_
executing its own shutdown hook.
Do you have any means to test this fix for your scenario?

> Java 7u7, Surefire with JUnit {{forkMode="perthread"}} + {{threadCount="1"}}
> + {{reuseForks="true"}}. After pressing Ctrl-C to stop the Maven test run,
> the process hangs and must be killed with SIGKILL. From the thread dump,
> {{CommandLineUtils.ProcessHook}} and {{StreamFeeder}} look responsible.
