Well, each parallel fetchmail will require one separate flag. If there
are only a limited number of flags available (and if we omit flags
like \Answered and \Flagged which are treated specially by almost all
email readers), then there will be unnecessary conflicts and
confusion. This effort is worth it only if their are servers supports
custom flags. The coding is (probably) going to be the same for both
available and custom flags. However, the safer thing to do would be to
go for UIDs.

Oops. Ignore.
