Well, Fabio could give you a more definite answer but I don't think it
would be collected.

Lua's GC does not shrink tables, only a rehash (potentially) does, and a rehash will not be triggered while there are free hash slots available, so you do not have to worry about the table shrinking under you. Roberto's chapter in "Lua Programming Gems" has more information (Chapter 2).
