I've found a workaround!  You need to tell bash to ignore SIGHUP.  (This
will also be inherited by processes started by the shell).

I added the following to /etc/profile, so that the shell will ignore
SIGHUP in an interactive session started by sshd:

# Fix to sshd problem (any Windows logout kills interactive ssh sessions)
if [ -n "$SSH_TTY" ]; then
   trap '' SIGHUP
fi
