Bug#425314: Cause identified + workaround ($HOME in use after session closed)

That info really helped me!

startkde (to which /usr/bin/x-session-manager is symlinked) runs kdeinit,
which is then - as you said - reparented to init.  startkde then runs
ksmserver and passes session management to it.

After ksmserver has terminated, the startkde script continues with some
cleanup actions, among which there is a call to 'kdeinit_shutdown'.
However, it does not wait for a confirmation, it just proceeds with further
cleanup routines and then terminates.

Adding a simple 'sleep 2' after the call to kdeinit_shutdown fixed the
problem for me, libpam-umount cleanly unmounts my $HOME.

I can live with the workaround, however it would be really nice if the
maintainers could find an alternative solution for the problem.

Thanks for helping me resolve the issue!
