Asuming that:
- msgsender is nonblocking

- compacting is non blocking (insert processEvents there)
o If we are getting mail, stop it (but don´t lose something!)
o If we are sending mail, go on UNLESS this was called by SM,
in which case stop ASAP that too (can we warn? should we continue
on next start?)
o If we are compacting, or expunging, go on UNLESS this was SM call.
In that case stop compacting ASAP and continue on next start, before
touching any folders.

Windows will take care of themselves (composer should dump
it´s messages, if any but not in deadMail)
declare us ready for the End of the Session
No, normal quit call
All windows are off. Anything to do, should compact or sender sends?
Yes, maybe put an icon in panel as a sign of life
Folder manager, go compacting (*except* outbox and sent-mail!)
if sender sending, connect us to his finished slot, declare us ready
for quit and wait for senderFinished
if not, Folder manager, go compact sent-mail and outbox

good, Folder manager go compact sent-mail and outbox
clean up stage1 (release folders and config, unregister from dcop)
