I have now tried that on the VMWare ESX server and I actually got

        normal completion after 1000000 iterations

as a result, so I guess it doesn't have to do with the timer thing!?
I also upgraded to Postfix 2.7, without VDA cause this time because this
server wasn't meant to have that patch in the first place, and I've been
watching the queue for a couple of minutes and the double-bounce
messages seems to go away as they should.
I'm gonna keep looking though, to see if it gets filled again but it
Looks like the upgrade fixed it.
I can report back at the end of the day to see if it's actually fixed.

Thanks a lot Wietse for all your help! I'm really grateful.
