Tim J. Robbins 613fcc1359 Do not allow a cached vnode to be shared among multiple mounts of the same 
kind of pseudofs-based filesystem. Fixes (at least) one problem where
when procfs is mounted mupltiple times, trying to unmount one will often
cause the wrong one to get unmounted, and other problem where mounting
one procfs on top of another caused the kernel to lock up.
