Phoenix occasionally hangs on ctrl-c

Occasionally when i ctrl-c my phoenix application it does not exit properly.
It prints a message indicating that the JVM is exiting but it never returns
to the command prompt. The only way to terminate the application is to kill
my window. I am running Phoenix 4.0.2 on my W2K box.

Anyone else seen this problem?

cheers

Jim, did you try to press ctrl-break at this point? Normally it prints
stack traces, but I'm not sure if this feature works during shutdown. It
may help you trace the problem if it really is what Ulrich suggested.

Yes, this can happen, when one of your components doesn't release its 
resources. For example, maybe you have a block with a dispose() method 
and Phoenix hangs there. Or maybe you have some connection open and 
Phoenix/the JVM can't close it.
