** Description changed:
+ [Impact]
+ Ubuntu users wishing to run updates, potentially with specific combinations
of customized theming on their desktop.
+
+ [Test case]
+ 1) Run update-manager
+ 2) Apply updates (this should include an update that requires reboot, such as
a kernel update, system library (libc?)...
+ 3) Let the "This computer needs to restart" dialog appear.
+
+ [Regression potential]
+ Failure of the "restart" dialog to appear or screen/window corruption when
this dialog appears should be investigated as possible regressions. It is also
possible that the behavior of the window changes in that its size might not
remain static.
+
+
+ ---
+
After installing certain updates (kernel, system libraries, etc.), the
"The computer needs to restart" dialog appears periodically, prompting
the user to restart the system.
That dialog eats a constant 8-10% of CPU time. That's the issue. (Yes,
update-manager is niced to 10, but why consuming *any* CPU at all for
showing a static dialog?)
