This is an excellent idea. Although I must think first which is the best way
to implement such a flag, I think that would be feasible (and much more
efficient than the present approach). Then, if the user do *lots* of
deletions, he can always use the "ptrepack" utility in order to physically
get rid of the rows marked as deleted.
