The cyrus imap people came up with an elegant solution to people doing
this kind of thing to their mail accounts.
Expunging the contents of a mailbox will not actually remove the
contents till some number of days later.
There is something to be said for deletion to trash.
I wonder if anybody has hacked the unlink systemcall to provide a safe
delete.
Something like moving the files to something like a lost_and_found type
of directory where it can be cleaned out after some time period or based
on free space requirements.
As an aside there is an extundelete but I am not sure how well it works.
