I would call it malfunctioning, it's deliberately breaking tcp/ip by the
sounds of it. You say it's to prevent DOS attacks, but isn't that
exactly what it's caused itself?

I experimented with this following the last round of borked firewalls
and it's virtually impossible to do without screwing up pgAdmin
completely - there are all sorts of threading/concurrency problems that
would take a massive rewrite to sort out - something I'm not prepared to
do to work around a problem caused by a firewall that doesn't implement
TCP/IP properly.

Agreed, I'm certain that's the response you will get (I've seen it
before).
