So this is the right way todo it. Why did you have the previous patch 15
at all given you've used O_NONBLOCK here ?
I thought that with a buffer bigger than the capacity of a pipe we
wouldn't be able to make write progress but that's not the case but it
fills up the pipe with whatever fits. I'll drop the MIN() stuff.
