My idea is that when we are packaging the events for the client we can
scan the events we have already queued to be sent to the client, and if
the events are the same we toss the one out. A couple questions.. (I
haven't gotten a firm grasp on FAM/gamin yet) does the client (aka
nautilus,etc) ask for all pending events ? or do we just push them down
a fd and nautilus reads them whenever it feels like it?

Either way I think flow control and event merging shouldn't be too hard.
We just need a staging ground for 'new events' where we could batch them
up and say once per second send them off to the clients or fd.

We should be able to add this right? It shouldn't affect the fam API,
just when gamin is shutting down call a backend shutdown callback.
