It would be more interesting if it really were in user space.  The
inode pager is a kernel process and basically allows paging to
anonymous files.  Access to inodes is done within the kernel, not
in user space.  (This is in Mach 2.5.)

It works well now.  The one thing that might bother some is that
after you shut down it leaves unreferenced files in the filesystem.
Fsck gets rid of them, natch.
