The worker threads are supposed to finish the tasks. If there are no worker threads there's nothing to wait on. Instead, while the calling thread is waiting, it should pop tasks off the queue and execute them. Furthermore, put() should throw if new tasks are placed on the queue while it's in this state. Will make a pull request soon. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
