Let me know if you want me to split it up or ANY changes and I'll get onto
it asap.
Maybe somebody could grab the code and check it out in the context of
specifying some filters. This will prevent those messages from coming to
the vehicle implementation at all.. and even from going through the poller
queue. It is non-blocking meaning that the filter is briefly
inopperational while the filter is being modified.
