Sure, I'll take that into account.

No.
That would be done only during a proper unmount or idle time.
As this block just contains ready_to_use block info,
that can be reconstructed, on remount.
Because any updation on fixed intervals will not be of use.
Neither will it be feasbale to update the TOKEN_BLOCK on every erase.
Please do comment.
