Using WSJT-X 1.6.0, I am receiving two (2) identical UDP status messages

Is this a defect or by design?
Hi Laurie,
neither, there are several points in the WSJT-X source code where events
are being processed that warrant a status update being sent to the UDP
server. In general these are the same points at which the
wsjtx_status.txt file is updated. No effort is made to optimize
redundant status updates.

Bill,
These Status packets are being sent when there is NO change in status.
* What is the purpose of these status packets sent at the 50 seconds
(just prior to decode processing it appears)?
* What is the purpose of sending a second duplicate status packet just
after the first packet?
The first packet could perhaps be useful as a heartbeat/keepalive type
message. The second packet is redundant.
I am testing with 10 WSJT-X instances running, under both Windows and
Linux (Ubuntu) environments, and am seeing these unneeded status packets
(for no status change) consistently from ALL running instances.
This 50 second status packet has not always been present. It is not
present in the 1.5.0 release. It appears to have been added deliberately
or may be an artefact of some testing that was not removed prior to the
1.6.0 compilation.
