Probably it is just painfully slow.. I've seen that couple of times, but
never really figured out why that happens. It has disappeared from my
current setup, though.

TShark 1.10.6 (v1.10.6 from master-1.10)

I was thinking of running a loop doing the check_frame_at_gate() calls
for the first address pair until the frame is seen or some maximum time
(10 seconds?) each reached (and a small sleep between calls). Obviously
that is not going to do much if running tshark is as slow as it is in
your case, but it should allow this to exit pretty quickly in case the
tshark step works properly.
