find_object() does not swap in an object; status() does, because some of
the information needed by that function is swapped out.  However,
status() only swaps in the first sector of an object's dataspace.
Calling a function in an object would cause much more of the object
to be loaded in memory.

If you want to avoid any disk access, you may want to cache some of the
information from status(obj) in your object daemon.
