Just to reply to myself once again,
System.Event (which isn't hidden) re-exports (un)registerFd and other
functions I need for this.
So I can implement all this myself. The only thing I can't do is ask
the RTS's eventmanager to watch the fds for me, but I can just create
my own ("new" constructor
Yep, that's like the workaround I'm using right now.
I create an empty mvar, fire up 2 threads that will wait for an fd and
tryPutMVar afterwards.
My original thread justs gets the MVar to wait for any of the 2
fd-waiting-threads to complete.
But however light threads may be, I still think this mig

Or you could wait for each fd in its own thread (those are really

Hi all,
I read the paper about the new ghc7 event handling IO manager goodies.
This is all very exciting stuff. I didn't know GHC's RTS had these
smart async-IO facilities.
The paper pointed me at threadWaitRead/threadWaitWrite.
While very nice the way they are, I would also like to be able to wai
