Log Message:
Add support for the EVFILT_EMPTY filter, which is activated when the
write buffer associated with the file descriptor is empty.  This is
currently implemented only for sockets, and is intended primarily to
provide visibility to applications that all previously written data
has been acknowledged by the TCP layer on the receiver.  Compatible
with the same filter in FreeBSD.
