OK - I've run a couple of quick tests.

1. The bug didn't go away when I reverted to the previous version of
sshd.

2. If I run an explicit command using ssh, it doesn't get killed when a
Windows user logs out.  I suspect that this has something to do with the fact
that such processes have no virtual terminal associated with them.  For
example, the following process will stay around after a logout:

ssh <hostname> bash
