There is a symbol in */driver.c called LITTLE_DUMPERS (near line 90).
The default is 3.  The "little" (first 3) dumpers take items from the
front of the queue.  All the rest of the dumpers (up to "inparallel")
take items from the end of the queue.

The queue is ordered by estimated dump time, which is based on size and
historically how fast the image is processed.

So in the normal case, if you have inparallel set to the default (10),
three dumpers will be working on the little (short) backups and the rest
will be working on the big ones, all subject to the other restrictions
you have (e.g. maxdumps, interface speed, etc).  More on the logic of
this is in the original papers at ftp.amanda.org, as I recall.
