How thread safe are promises?

See original GitHub issue

After reading through the source for some time I do not see any use of locks (like the imported and ignored from threading import RLock) to protect one thread adding a callback to a promise instance from another thread that is resolving/rejecting that promise…

So is such use of a promise invalid or does it work because of the GIL? … or something else?

Thanks for the awesome code!
