Well I have data from two sources, stdin and the calculation
thread. If I was doing this in C, I'd probably use a pipe for the
calculation data and then do select on the two file descriptors.
There is a select package:
http://hackage.haskell.org/package/select
but I was wondering if there was a more idiomatic Haskell way
of dealing with inputs from more than one source.
There are list arrows, and also coroutines in many guises including
pipes, conduits, and iteratees. These are all co-operative concurrency,
however, and I can't tell if your problem requires pre-emptive threads.
