I spoke too soon, it can still degrade, it's just takes longer to 
happen.  This is with `ping -i .25 192.168.1.1`

It'll be very stable, ping times of less than 2ms, then dropped packets 
and jumping up to high ping times.  My messages file doesn't report 
anything noticeable other than losing network and regaining.
