Creating new objects (table , string, closure, coroutine, etc) and Inserting key into table may need more memory.

If you need a fixed amount of memory , I think you can define a lua_Alloc and set the memory limit. You can let lua_Alloc returns NULL when exceed the memory limit, and lua will collect immediately.
