1603 | since that's synchronous, and we might end up blocking on | |
1604 | it. Specifically: given that PID 1 might block on | |
1605 | dbus-daemon during IPC, and dbus-daemon is logging to us, | |
1606 | and might hence block on us, we might end up in a deadlock | |
1607 | if we block on sending PID 1 notification messages -- by | |
1608 | generating a full blocking circle. To avoid this, let's | |
1609 | create a non-blocking socket, and connect it to the | |
1610 | notification socket, and then wait for POLLOUT before we | |
1611 | send anything. This should efficiently avoid any deadlocks, | |
1612 | as we'll never block on PID 1, hence PID 1 can safely block | |
1613 | on dbus-daemon which can safely block on us again. | |
