I've got one more question now. Suppose I want to do the same thing

a way to tell whether the first process wants input, and if not, wait

Not readily, because if the process ends up outputting more than a
certain amount (_PIPE_BUF kernel parameter) of data your program will
deadlock. I think you need to forkIO and use MVars to synchronize.
