I wonder how this works when one runs test in parallel (something I always enable in any project). By this I mean configuring JUnit to run as many tests as cores are available to speed up the run of the whole test suite.
I took a peek at the code and I have the impression it doesn't work that well as it hooks into when a thread is started. Also, I'm not sure if this works with fibers.
