Well I tried using shared_ptrs and at the end of the function, setting 
them to nil in Lua but it doesnt decrement the use_count:

-- Lua
-- entity is a boost::shared_ptr<Entity> in c++
-- entity.use_count() in c++ = 3
mission["enter"] = function( entity )
{
   entity:DoSomething()
   entity = nil
}
-- entity.use_count() in c++ = 4

It appears the 'entity = nil' line has no effect.

I'll try weak pointers
