The objects are either very small objects that are allocated all in lua 
(like a vector with 3 floats) or bigger objects where lua just keeps a 
pointer to the object. The bigger objects all have their lifetime 
controlled by C (the pointer in lua is just a weak reference) so it is 
only the space occupied by the pointers that is affected by GC performance.

So 4 -- 30 bytes per object.
