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.

Really? Please at least use:

My proposition is to add function like getmainthreadid() -> int which return ident for main thread (I know function name is not perfect, please guess better one). Signal module already has required data as internal variable static long mainthread; I just guess to expose this value to python. Thoughts?
