The kernel has a ref on the other end of the pipe because it's still
available to be opened and used again.  You'll never see EOF.

There were a couple of missing calls to close in the code I sent, but
even if you close everything in sight, you'll never see EOF. There's a
twisty maze of circular dependencies holding the structure up.

As I said in the beginning, this trick is suitable for continuous
files such as devices, but not for regular files.
