Comment(by nomeata):
Julien Cristau solved the riddle: epoll_create1() (note the 1) is only
available on newer kernels, so if ghc is built on a new kernel it will use
epoll_create1() instead of epoll_create() and it will not run on older
kernels. See http://lists.debian.org/debian-devel/2011/03/msg00407.html.
How should we solve this? Unconditionally use epoll_create()? Or come up
with a run-time check as to which one is available?
