Additional work is needed to allow ThreadManager::removeWorker() to do the right thing when many threads arrive at it at the same time. In gdb I found that workerCount_ was 10 but workerMaxCount_ was 0; the stop behavior for ThreadManager calls removeWorker(workerCount_) and gets an exception, which eventually causes a core. This is why, for this submission, I left it as stated.
