Comment 6 for bug 965686

Mathieu, we could run the counterpart of "evolution --force-shutdown" in the preinst if the upgrade detects that we are upgrading from an old version? I. e. kill all running e-a-n instances? There might be a more elegant solution to detect that situation at runtime, but I don't think we should waste too much time on this. After the upgrade you'll need to reboot anyway.
