That was the problem, I now no longer get a stack overflow. >> As a side note, it's necessary to add parallelStop, to kill all the >> threads - or you get thread blocked exceptions being raised. > > alternatively, you can catch this exception in addWorker I could, but it wouldn't be that easy to tell if the reason for the deadlock was the program finishing a real deadlock occurring in the system. I'd rather not catch exceptions where possible.
