Raise an exception if an error appears on the pipes to our children, and make
sure that the child's pipes are closed even under that exception. Move the
handling of POLLHUP to the end of the loop, so that we guarantee to read any
remaining data from the child if POLLHUP and POLLIN appear at the same time.
