how does this compare to the kqueue mechanism found in {Free,Net}BSD?
(see http://people.freebsd.org/~jlemon/papers/kqueue.pdf)

i especially like their combined event update/event wait,
needing only one syscall per poll while building a changelist in
userspace...

a replacement for poll/select is _really_ needed.
but i think we should use existing interfaces if possible,
to reduce the changes needed in userspace.
