Hardly --- how's that going to pass a notify name? Also, a lot of
people want some payload data in a notify, not just a condition name;
any reimplementation that doesn't address that desire probably won't
get accepted.
There's lots of threads in the -hackers archives about reimplementing
listen/notify in a saner fashion. Personally I lean towards using
something much like the sinval queue.
