I don't understand. How is the user to "bloat up some objects" if he has
crossed limitations or ran out of resources?  And why would this lead to an
out-of-memory condition (assuming you swap out things according to a LRU
scheme)?  If you know how much memory is available then I don't really see
how this could be a problem. If you don't, then you could preallocate a
chunk large enough to deal with exceptions whenever out-of-memory is thrown,
and clean up whenever it gets thrown.  No?

I am probably the one who is missing something...
