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.
