Comment(by tibbe):

 So it's only possible to detect this at run-time? Here's what we currently
 do:

 {{{
 epollCreate :: IO EPollFd
 epollCreate = do
   fd <- throwErrnoIfMinus1 "epollCreate" $
 #if defined(HAVE_EPOLL_CREATE1)
         c_epoll_create1 (#const EPOLL_CLOEXEC)
 #else
         c_epoll_create 256 -- argument is ignored
   setCloseOnExec fd
 #endif
   let !epollFd' = EPollFd fd
   return epollFd'
 }}}

 I'd be fine to include a run-time check if necessary.

 Note: I'll be out on vacation and only have very sporadic access to email
 between March 10-26. If you have more questions about the current design
 please ask Bryan O'Sullivan.
