watcher: Prevent race condition spawning multiple watcher threads
If file descriptors get added and removed in rapid succession, the active
watcher thread might not take notice of it and continues running. However, add()
spawns a watcher thread whenever a file descriptor is added to an empty set.
This could result in multiple watcher threads, which is fixed by a proper
check for running watchers.
