Old immutable objects are only "checked" at full collections. Usually
you have to run a full collection from time to time, but this is much
less frequent than "short" collections. For some particular tunned
applications, you can completely avoid full collections.

Lua still have to check that nobody changes such objects, so the overhead
would be similar (small in both cases). But with a generational collection
Lua would detect those "const" objects for you.
