Timed Out Machine Returns

Since the swarm server can no longer directly connect to a slave, it can't kill 
any running processes once they've timed out.

This means it is possible for the server to mark as test as timed out, but then 
have the test still return at a later time.

Currently we just consider this a repeated result (since we added a result of 
timing out earlier) and the fact the we just got data from a timed out test 
isn't recorded anywhere.

It is not clear what (if anything), should be done in this case, so I'm just 
adding this bug to remind us of this issue.
