Comment 72 for bug 1421009

There was a tip from tvoss to try to use QDBusConnection::connectToBus instead of QDBusConnection::sessionBus() / systemBus(), to minimize sharing of DBus connections.

There are 3 PPA:s now all doing that:

- https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-007/ - Pete's changes to libusermetrics only (note, Pete is updating his branch but the current build is from his first revision that only updated systemBus calls)
- https://launchpad.net/~canonical-qt5-edgers/+archive/qt5-proper/ - Pete's and my changes to libusermetrics
- https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-010/ - Pete's and my changes to libusermetrics + similar

Using 007, my mako is now at 105 reboots and counting.
