The most obvious way to do this seems to me to have the clonable object 
as the head of a double linked list. This adds an overhead to all clones 
of two variables -- not a terrible price to pay for what I'd consider an 
absolutely vital piece of book-keeping.

The traditional, no-object-manager approach is, of course, just this:

for (i = 0; i < sizeof(status()[ST_OTABSIZE]); i ++) {
   if (find_object("/foo/bar#" + i)) {
     /* got one */
   }
}

which is perfectly adequate for emergency maintenance and such (for 
example, if you ever needed to recreate the linked list mentioned above).
