Main thread is slightly different from others. Signals can be subscribed from main thread only. Tulip has special logic for main thread. In application code we can explicitly know which thread is executed, main or not. But from library it's not easy. Tulip uses check like threading.currentthread().name == 'MainThread' This approach has a problem: thread name is writable attribute and can be changed by user code.

Please at least use:

isinstance(threading.current_thread(), threading._MainThread) True

But really, what we need is a threading.main_thread() function.

(Apologies for the previous incomplete reply (keyboard mishap))

Antoine.
