And the other way around. If class "Foo" is defined in the parent scope, can the child thread create a new instance of "Foo"?

So that thread could a) send messages to other threads (not just setting properties, of course, messaging could be emulated with properties but a more messaging like API might be appropriate) and b) has a mutex object which can be used to manage access to shared resources. What about the following: Thread 1: $mgr = MutexManager::getInstance(); $mutex = $mgr->create('foo'); Thread 2: $mgr = MutexManager::getInstance() $mutex = $mgr->fetch('foo'); while (!$mutex->aquire()); access_shared_resource(); Messaging: Thread 1: $m = ThreadMessenger::getInstance(); $m->send('my message'); Thread 2: $m = ThreadMessenger::getInstance(); while ($msg = $m->receive()) { if ($msg == 'my message') { do_something(); } } Please don't get me wrong. I really like having movement in the threads area. While threads make it easy to blow away your foot, there are some use cases where they are really helpful. I just think load currently :) cu, Lars
