I should have mentioned that the account I was using for ssh DOES have a
correct host key entry for the remote host - the error message is itself
erroneous.  Although I think we're getting on track here - it looks like
the problem is happening when I su into a different account and try to
ssh from the su'ed account (which also has the host key) - after su'ing,
the tty device remains owned by the base user with respect to my new
EUID, which appears to make ssh outbound break.
