 Reopening this based on reports that this switches the deadlock into a
 spin. While better, obviously not optimal.

 This probably means there's some data "stuck" in a pipe that we're not
 picking up. This would also explain why the buffer space fills up. I've
 got a core dump to investigate and will follow it up.
