#4475 [HHQ-4327] Agent SenderThread sending same measurements more

[Hyperic Team]

http://jira.hyperic.com/browse/HHQ-4327
This is easily reproducible with 4.5 agent. Agent is sending 2 or more measurement data points in the same SenderThread batch.

Here's a sample debug log from agent. Note that measurement id 10001 and 10645 are sent twice in the same batch. Timestamp for id 10001 values were 15 ms apart but 1 minute apart for 10645

Here's corresponding server.log entries. Note that server woo-doo makes both measurement timestamps same.
