Could you explain how you combine AEM with epoll, as that is new to me?
Anyway I think the general "feeling" seems to be, that of those three
methods you listed, epoll has most potential use in CGL.

I have said this earlier and will now say it again: until you get the
other NEP's in CGL convinced of AEM's "exceptional qualities", AEM is 
not going any further in CGL, meaning that I will be happy to keep it
as a PoC reference, but that is it.

And now that we seem to have an alternative (until proven otherwise)
with libevent + epoll, WHICH IS ALREADY MAINLINED (i.e. epoll is in
2.5/2.6 and I can download libevent RPM to my rh9), I strongly suggest
that Specs-sg add that as a PoC reference to relevant requirements.
