_MainThread can be used as workaround, but adding public function makes value.
Oleg, as I understand _MainThread is a class, not class instance, test for threading._MainThread.ident doesn't make sense.

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. You can test threading.currentthread().class is threading.MainThread or threading.currentthread().ident == threading.MainThread.ident
My proposition is to add function like getmainthreadid() -> int which return ident for main thread threading.MainThread.ident ? Oleg. -- Oleg Broytman http://phdru.name/ phd at phdru.name Programmers don't die, they just GOSUB without RETURN.
