I only see (looking at 5.2 code) luaH_resizearray called when
OP_SETLIST is handled; it may mean that all other assignments will
either have to fit the allocated array or will go to the hash part.
The keys will be rehashed and possibly re-allocated to the array part
when "rehash" is done; this happens when there is no free place in the
hash for a new key.
