This could happen with old versions of OpenSSH: they did not correctly
handle the case where pty allocation failed.
This was fixed in 5.6. From http://www.openssh.com/txt/release-5.6:
Kill channel when pty allocation requests fail. Fixed stuck client
if the server refuses pty allocation (bz#1698)

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
