qmail calls this 'named pipe bug 1'. The workaround (which screen
probably uses too) is to let the process doing the select() also have
one fd opened for writing on the pipe. With that write-open, select()
will only return if there is actual data waiting inside the pipe.
I have filed a PR (19871) for this I think about 2 months ago, somebody
submitted a patch but I never gotten around to testing it.
I surely do think this behaviour is broken.
