Hmm, the phase variable doesn't change, but could the element at
'owner->hash[idx]' change? I'm not sure about that. The loop is supposed
to handle the case that the hash table grows; could that replace the
element at 'owner->hash[idx]' with something else, with different phase?
The check is very cheap, so I'm inclined to keep it to be sure.
