Recursion on channel closing

I'm using Arquillian Cube (which uses UT 1.3 branch) to perform some tests, and at a given time, the test execution apparently freezes, which a high usage of CPU.

When we get the Thread dump, we see a recursion pattern in the frozen thread. It's attached (loop.txt).

It never finishes, so, I have to cancel my test execution at that point.
