Imagine a laptop on wireless going into suspend for a few minutes,
then getting woken up. If you're lucky today, the TCP connections
survive.

If you check for stuck TCP connections right after resume, you could
have problems because the wireless hasn't negotiated encryption keys
at that point. Isn't that a concern?
