#1520: Use Linux's signalfd() instead of pipe() to deliver signals to the IO
manager

-------------------------------+--------------------------------------------
As pointed out to me by dcoutts, Linux has a new API that enables signals
and other events to be delivered via a file descriptor, and hence used
with select()/poll()/epoll(). The new API went into Linux 2.6.22:

We could use this in GHC's IO manager to avoid the hacky use of pipe() for
the same purpose.
