That's how I expected it to work as well, but my observation tend to
show not even the priority is respected, which is ... confusing and I
think is causing most of the pain we are experiencing with the races
at startup.

See https://bugzilla.xfce.org/show_bug.cgi?id=15712 and
https://bugzilla.xfce.org/show_bug.cgi?id=15725

There is something seriously fishy there...
