Each fd set has a boolean that keeps track of whether or not the fd set is in use by a monitor connection. When a monitor disconnects, all fds that are members of an fd set with refcount of zero are closed. This prevents any fd leakage associated with a client disconnect prior to using a passed fd.

The lifecycle of fdsets and fds isn't clear to me. It seems like just a refcount in fdset should handle this without extra fields like in_use. Stefan
