One possibility is to have some form of room daemon that simply clears out 
any rooms that have expired beyond reset only if they don't contain 
anything. In that scenario the room registers itself on creation with the 
daemon and indicates how long to go without reset and if the room can be 
removed. Then the daemon (Which hangs around on a long call_out) just runs 
through its list of rooms, at say 10 rooms every pass to stop it sucking up 
ticks, and resets any that are beyond their reset time, and destructs any 
that aren't in use and can be removed (Ie Are flagged as removable, have no 
players, mobile NPCs etc). That should keep the number of rooms that are 
active down to a bare minimum, with anything not active being created as 
player's enter, helping out with mud resources.
You can take that daemon idea and make its policies as complex as you like 
and have the effects reproduced throughout the whole mud as opposed to 
recoding individual rooms (This is probably used in quite a few libs). 
Possibly the most elegant expression of this is to code your object manager 
in such a way that it not only keeps track of object issues but also keeps 
track of all object resets/removals etc. In that scheme everything 
(Rooms/players/NPCs etc) get treated in the same way, as simple objects 
that flag themselves up as resetting/removable etc on creation. I guess it 
might even help out with creating new issues of objects as you could check 
if an object is a reseting type, and simply flag it to do a recompilation 
on the next reset instead of an ordinary reset, thereby making it current 
issue without the object manager recompiling it immediately.

Hope that makes some sense, it seemed clear until I read through it again :>

Cheers,
