old processes stay around after login,logout and eat cpu

[Sebastien Bacher]

Using quantal beta2:
- log in
- log out
- log in again

when doing that sometimes a signond process from the first session (which got closed) is staying around next to the new one and eating cpu

gdb on it:

Not high priority, as it's not such a common use case.

No reports of this after 2012; assuming this has long been fixed. If not, please reopen.
