After some more testing I can see that it gets hung up here most of
the time, but not every time:

debug1: Failed to acquire GSS-API credentials for any mechanisms (No
credentials were supplied, or the credentials were unavailable or
debug1: SSH2_MSG_KEXINIT sent

I do have gssapi set to no in /etc/ssh/ssh_config on the client and in
sshd_config on the server.
