Have you addressed the concerns of:

	- Acquiring the number of named filters.

	- Need 3 filter entry points for them to be truly useful.

that have been raised each time kqueue has been discussed?

Sadly, the easy one to implement (name-to-number) is the one that doens't
directly affect the kevent API itself -- the more complicated one, the
3-filter-entry-points, does.  And since it does change things a bit, we
need to have that implemented before its brought into our tree.
