So, attempting to

I don't think the things can lead to OOM error, even in finalizer.
The problem may ocur when we use 'collectgarbage' inside of finalizer.
Do concatenating, creating table, and adding a new key lead to any single 'step' in garbage collecting algorithm?

They allocate memory. Memory allocations can trigger the GC if there's not enough available.
