| 1614 | since that's synchronous, and we might end up blocking on | |||
| 1615 | it. Specifically: given that PID 1 might block on | |||
| 1616 | dbus-daemon during IPC, and dbus-daemon is logging to us, | |||
| 1617 | and might hence block on us, we might end up in a deadlock | |||
| 1618 | if we block on sending PID 1 notification messages — by | |||
| 1619 | generating a full blocking circle. To avoid this, let's | |||
| 1620 | create a non-blocking socket, and connect it to the | |||
| 1621 | notification socket, and then wait for POLLOUT before we | |||
| 1622 | send anything. This should efficiently avoid any deadlocks, | |||
| 1623 | as we'll never block on PID 1, hence PID 1 can safely block | |||
| 1624 | on dbus-daemon which can safely block on us again. | |||
