I'm not completely sure, but I think that Bacula figures out what media
it is going to use before it calls RunBeforeJob. This would mean that if
you schedule your VirtualFull while your Incremental is running, the
VirtualFull will not include the Incremental backup, no matter how much
you wait inside the VirtualFull's RunBeforeJob script.

Does anyone know for sure?
