I guess some checkup on plasma is needed in the following scenario's:
- user adds a faulty plasmoid which crashes plasma. Plasma restarts, crashes
again.
Now plasma starts again, but the broken plasmoid is disabled, and the user
is notified of that using of course a non-modal dialog.

- plasmoid shows an icon for new version available. Mouse-over shows a info
widget with a link: click to update. the applet shows it's downloading &
upgrading (as does the central progress thingy), when done, it restarts the
applet (starting the new one). Crash. Restart plasma. Crash.
Now plasma starts again, but (surprise) the upgrade has been reverted, and
the user is notified of that using of course a non-modal dialog. Only when a
new version of the applet comes out is the user notified of an available
update again.

I guess for this kind off stuff, a sperate process is needed to monitor
stuff. When an applet is upgraded or installed, before it is started, plasma
should notify this monitor process, so it would be prepared to take the
right action (revert changes) if crashes happen.

OK, I actually thought about all this yesterday during my weekly shower ;-)
