`std.signal` implementation is written like it is called from a single thread
or explicitly synchronized. The reality is on objects collecting GC calls
dispose events of finalizing object from its thread. So `unhook` can be called
in a middle of `emit`, `connect`, or `disconnect` freezed in other thread.
