Alas, yes.
We should just make sure modules never crash! ;-)
Seriously, if panel or desktop app crashes - this is also not a very
pleasant event. I remember that in Razor session monitors modules
(processes) and restarts them if needed. With this new idea we also can
have lightweight monitor app.
When launcher starts - it register itself in the monitor app, before good
exit it unregisters itself, on crash monitor restarts the launcher with
needed modules.
Actually, maybe the idea is not so bad.
