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.current_thread().class is threading._MainThread or threading.current_thread().ident == threading._MainThread.ident

My proposition is to add function like getmainthreadid() -> int which return ident for main thread

threading._MainThread.ident ?

       Programmers don't die, they just GOSUB without RETURN.
