Re: Extreme memory usage

Ok, I think I found the way to reproduce the problem, or at least, how it's happening to me.

I haven't mentioned it yet, but I have experienced problems in latest previous releases of gnome-shell with the multi user usage. In a nutshell, I always leave on/suspended my desktop, and we are mainly 2 users using it:
- Opening a session with an VNC client doesn't work OK due to some dbus problem, and you are presented with a "Something went wrong" screen
- Leaving one user locked, doing stuff in the second for a long time and going back to the first one makes sometimes to be presented with the "Something went wrong" screen

This second thing, now seems to be the one that makes gnome shell take up that much memory. Instead of crashing, seems that the next time you unlock, it will take a lot of memory.

Therefore to reproduce (AFAIK):
- Login with user A
- Use normal apps: chromium, gnome-terminal, evince
- Switch account to user B
- Use normally
- Switch back to user A.

Take into account that it might be something that stacks up with time, so use A for a long time, use B for some time (5 hours or so), leave inactive between both switches, and then go back to A.

Hope this helps!

It's important to find a steps recipe to reproduce the problem. In this
case, steps from a fresh OS installation or Live-CD session.
