What happens when you 'delete' a record? Does it disappear immediately,
or is it merely marked for deletion?
If it is marked for deletion, can it be unmarked? Will a marked record
be removed when the file is closed, or does the file need to be
If it is merely marked, then I think the best option is 1, or possibly
4 if the file is compacted when closed.
