SshMachine hangs forever if hostname mismatches the IP key

[xNinjaKittyx]

In scenarios where hostname key is correct, but the IP key is incorrect, plumbum doesn't spit an error, but instead hangs forever.

Warning: the ECDSA host key for 'myhostname' differs from the key for the IP address '192.168.1.123'
Offending key for IP in /root/.ssh/known_hosts:67
Matching host key in /root/.ssh/known_hosts:91
Are you sure you want to continue connecting (yes/no)?

In the scenarios where ssh key is incorrect or no key exists, it raises an exception (from what I remember...)

Slightly unrelated, but if there's a way to not use an identity file (yes I understand the risks), I would like to know this as well.
