Indeed, it shouldn't: pulseaudio checks for other running pulse
process before trying to start up, and exits in that case.

Did the upgrades by any chance happen to include systemd? pulseaudio
relies on XDG_RUNTIME_DIR, and some systemd upgrades (depends on exact
versions, I htink) mounted a new tmpfs on /run/user/<uid>. This could
have masked the old pulseaudio pid dir, and thus became invisible.
