ok, so:
nothing gets you epoll if you pass execution test
--enable-epoll gets epoll w/only compile test, no execution test (for
cross-compile people)
--disable-epoll just turns it off
pete? i understand your concern re: 2.6/2.4 people, but that should be a
dying breed at this point...one extra step for them so that we do the
right thing for the masses seems reasonable...

why don't we add a configure test that executes code to see if we get
ENOSYS?
that might be a good-enough solution. It leaves two issues:
- execution-based tests break cross compiling
- Pete didn't like that pvfs2 libraries compiled on 2.6 systems were
not portable to 2.4
For the former, we can just never use epoll if we are cross compiling
For the later, people in pw's situation can configure with
--disable-epoll
Fair enough?
