I would expect one system to fall off the network, when it is put into
kdb. However, why does it have any effect on the other system, which may
or may not be in kdb?

Let's say we have two test servers (A and B); and four test clients (1-4).
1 and 2 are being used to test performance on A, while 3 and 4 are being
inflicted on B.

kdb is activated on A, and from that moment, no network traffic passes
between B and its clients, 3 and 4.
