Spiros,

There's been a new directive added in recent versions.
In the bacula-sd.conf file, you can now add
Maximum Concurrent Jobs = <some number>

I use 6, but your mileage may vary.  Here's the section of the manual where 
it's been described:

http://www.bacula.org/5.0.x-manuals/en/main/main/New_Features_in_5_0_0.html#SECTION00510000000000000000

Here's how I've found it to work.  If you set that number to be 2, and you 
have more than 2 jobs running, the first two will be assigned to the 1st 
device, etc. There's more to it than that so you'll want to watch how it 
behaves.  Remember that you have to restart the storage daemon whenever you 
change it's config file--you can't re-load it.

Here's a snippet of my bacula-sd file that shows it in the Device section.

Autochanger {
   Name = Dell-PV136T
   Device = IBMLTO2-1, IBMLTO2-2
   Changer Command = "/opt/bacula/scripts/mtx-changer %c %o %S %a %d"
   Changer Device = /dev/sg4
}
Device {
   Name = IBMLTO2-1
   Drive Index = 0
   Media Type = LTO-2
   Archive Device = /dev/nst0
   Changer Device = /dev/sg4
   Maximum Concurrent Jobs = 6
