Fix glitch with switching users from QuickSettings
Since keyguard and systemui were merged into the same process to save
memory, they share the same Looper and graphics context. As a result,
there's no way to allow concurrent animation while keyguard inflates.
The workaround is to add a slight delay to allow the animation to finish.
