As it turns out I can't reproduce it anymore. Our test lab got
restructured and the cabling between machine changed (maybe even
different network switches, idk). Also the target got a firmware
update.

It looks more like the real problem was caused by the network
infrastructure than the host itself. And adding the additional delay in
the send path was just reducing the load which made the ssh session
working.

Given this, I don't think we currently need to touch this code. Though
the unbounded loop makes me a bit uneasy.
