Not in the least, there are programs which are supposed to stay running
even when you log out -- screen, vncserver, nohup'ed processes etc. Mind
that non-desktop oriented projects might not be that inclined to work
around the "desktop strangeness du jour" (background processes being
killed when logging out would count as such).

This would solve the problem above more cleanly.
