Are you sure this is not going to print lots of messages like this in

[stderr] Warning: Permanently added '192.168.122.99' (RSA) to the list
of known hosts.
A long time ago I suggested the /dev/fd solution to replace /dev/null
to cut down the number of those messages which gets printed
*everytime* ssh is run. Those messages could number in the hundreds
for long running tests.

The host_file got by os.tmpfile() is not available for "ssh -o
UserKnownHostsFile " on ubuntu 11.10 and will have the error
"Failed to add the host to the list of known hosts (/dev/fd/11)",
so the patch just replace it with '/dev/null'.

Yes, this will print the message mentioned by you. I understand your
solution now, but is there other solutions to avoid the error message
"Failed to add the host to the list of known hosts (/dev/fd/11)" ?
