openssh_tunnel does not take password authentication if first password is wrong

[SylvainCorlay]

When connecting to a remote kernel with

ipython qtconsole --ssh=host --existing connect_info

if the first password attempt is incorrect, the following attempts won't work event if one enters the correct password. Ping @ccordoba12, @minrk .

I assume your issue is on ipython and not on pyzmq/zeromq? Hit the wrong channel?

[SylvainCorlay]

The problem occurs in pyzmq. This example is just the simplest way to reproduce the issue.
