I know that the standard POP-3 daemon (from BSD, used by slackware) is not
creating any session lock. So it is possible for a user to have to pop3d
session at once and this result in corrupt folder (in fact, often the mail
get duplicated).

The problem is that sometime, user try to get their email and for
different reason are not patient enough and "try again". So mail program
then close the current POP session and start a new one. The original pop3d
take some time to close the connexion when it does some cleanup on the
incoming folder. This is enough time a new pop3d to start on the same
folder. Given there is not lock, some corruption exist.

The virtual pop3d daemon (create with the original BSD pop3d daemon from
slackware) has a session lock to prevent this problem and may be used as a
replacement for standard pop3d. The lock stuff may be folded back in the
original pop3d very easily is someone needs that.
