One problematic thing is that you cannot determine if a file system item is in
use or not.  A file system is in use if someone references a node of this file
system.  There are some rudimentary checks in unmount(), but they are by far
not sufficient.  I suppose we have to introduce thread-safe reference counts
for nodes and mount points.
