Andreas Gudian commented on SUREFIRE-946:
-----------------------------------------

Having thought about this over night, I'm pretty sure my 
Surefire946KillMainProcessInReusableForkIT does not yet test anything, as a) 
verifier does not fork by default in the current configuration, and b) I'd have 
to add some code to check if the process already terminated (e.g. by checking 
if the thread named {{Thread.currentThread().getName()+ "-ProcessKiller"}} is 
still alive). I'll fix that tonight.

> 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.
