It's definitely not a kernel crash. It just kills the current ssh
session. I'm at work now but will attempt to delve a little deeper
into this when I get home. I'm not alone - Jean Fabrice has
experienced similar problems - I'd posted something about this a week
or so back.
Like I said, I'll spend some time looking into this in more detail.
It's the least I can do compared to the considerable effort you and
others have put into the slug.
