The behavior of VT switching points toward a low-level bug, rather than
an application bug (cf. #437607):

0. After first login: X consumes 100% CPU
1. Alt+SysRQ+R (release KB, the VT switching seems to be disabled in default configuration?)
2. Alt+F1 (switch to VT1)
3. Something (Xorg?) causes the VT to switch immediately back to VT7
3b. The "Switch user" functionality in Gnome doesn't work either: VT switches always back to VT7
4. Log out from X, log then back in
5. X cpu consumption low
6. Alt+F1
7. Now the VT does not switch immediately back
7b. Also "Switch user" functionality works again.

It could be useful if the past/future me-tooers verified if they see
this same behavior vs. VT switching. There may be multiple causes for
100% cpu consumption, but to me the above seems too much of a
coincidence to be accidental.
