--- Comment #59 from Michael Catanzaro <mcatanzaro at igalia.com> ---
We could use prctl(PR_SET_PDEATHSIG) somewhere to give some chance of shutting down the DBusProxy in that case, and we probably want it anyway for the event of a UI process crash. I think currently the secondary processes kill themselves when they detect I/O hangup. Presumably the D-Bus proxy needs something more? Try testing by killing the UI process and seeing if the proxy process hangs around.
