Major revamping of host monitoring; use userhost, up timeouts, give up after 3 failures
Major revamping of host monitoring; use userhost, up timeouts, give up after 3 failures

We had many problems in the host monitoring.  First, we weren't using the username,
which is just wrong; it would cause repeated connections if not using the default
user.

Secondly, 3 seconds is WAY too short.  Not sure how that stood so long.  Let' s
use 15 seconds.

Finally, give up after 3 consecutive failures.  No sense in trying to poll forever.
We'll try again if they switch tabs to something else.
