Do you happen to know anything about it? I'm scratching my head how it's possible that process termination serializes with GUI... Maybe it hogs some lock on process descriptors which SendMessage also needs to grab for a moment to find the target process? I hope you didn't mean to say that every SendMessage call is completely serialized with each other.
