Fix `ls -laR | wc -l` hanging.
stat()-ing /proc/PID/fd/FD incremented but didn't decrement the refcount for FD. This behavior wasn't usually noticeable, but in the above case: - ls would never decrement the refcount of the write end of the pipe to 0. - This caused the write end of the pipe never to close. - wc would then hang read()-ing from the pipe.
