Efficiency is alway a point of course. But you have to keep track of
your field and you create a redundant data structure. You might run into
inconsistancy with it.
"My" solution is self-consistant, not redundant and you don't need write
operations during seeking for the fre entry. So maybe its even more
efficient.
