Module list is forgotten on multi start

[mkahvi]

If you have already running elimination process running, and hit the find the culprit button in modules list and start it, you lose your initial module list state.

This is mostly an issue if you start the process, fiddle with things, come back to it later, forgot you had one already running and have dialogs in the way and you remember you needed to run find the culprit.

It'd be better if the find the culprit dialog would recognize you already have elimination process running and prevent starting new one until the old one is resolved (and remind the user that such is actually in progress).
