Last line of output is always an exception

Same issue running latest release or HEAD.

from pssh import ParallelSSHClient

hosts = ['host1.fqdn', 'host2.fqdn']
client = ParallelSSHClient(hosts, proxy_host='gw.fqdn')
output = client.run_command('ls -l /home', sudo=False)

for host in output:
    for line in output[host]['stdout']:
        print "Host %s: %s" % (host, line)

Output:

Host host2.fqdn: drwx------  2 root          root          16384 Oct 22  2014 lost+found

Exception KeyError: KeyError(140473008761904,) in <module 'threading' from '/usr/lib64/python2.7/threading.pyc'> ignored

If I add more hosts, the exception moves to the last line of whatever the last host is.

This is coming from gevent, it's not this library's exception, and keeps cropping up depending on version of gevent and order of imports.

Can you please confirm version of gevent you have installed?

pip show gevent

gevent 1.0.2

Tested your gevent_exc_host_dedup_fix branch and it appears to fix the issue.
