Control-C during checkout doesn't cause bzr to exit

[Jean-Paul Calderone]

First I run bzr:

exarkun@charm:~$ bzr checkout sftp://launchpad.net/someinvalidurl

Then I hit ^C:

bzr: interrupted

But bzr is still running, so I hit ^C again:

Exception exceptions.KeyboardInterrupt in <bound method SFTPClient.__del__ of <paramiko.SFTPClient object at 0xb76fe1ec>> ignored

This time it actually exits. But a little while later, this output appears on my terminal:

ssh: connect to host launchpad.net port 22: Connection timed out

I think after the first interrupt bzr is trying to shut things down (run the finally blocks) and one of them is taking a long time. it may be that we're waiting for the ssh connection to close, but if we've not been able to establish a connection then we might need to kill ssh, rather than just close the pipe and wait for it to exit.
