[LDM #GBK-975146]: slight differences between files

Erik,

I didn't realize that the two LDM were requesting from each other as well as 
from
the upstream LDM-s -- in which case the timing of the comparison is irrelevant.

Basically, if there's more than a single path from the source of the data to the
final LDM, then the sequence of data-products as seen by the final LDM can 
differ
from the sequence sent by the source LDM due to some LDM's queue being too 
small.
Here's the sequence that could lead to that:

    1. Product 1 received from LDM A
    2. Product 2 received from LDM A
    3. Product 1 deleted from queue to make room for more products
    4. Product 1 received from LDM B
    5. Product 2 rejected from LDM B because it's already in the queue

The LDM will now relay/process products in the order 1, 2, 1.

The size of an LDM queue -- both the amount of data size and the number of
slots -- needs to be large enough that the minimum residence time of a product
in the queue is greater than the maximum latency parameter in the LDM registry.
And this must be true for every LDM between you and the source.

Regards,
Steve Emmerson
