    GEODE-2870: Local node function execution failure correctly returns e…

    …xception
    
    * Race condition and escaping synchronized block led to function possibly 
missing results
    * It was possible a remote node would enter the synchronized block after 
local node threw exception
    * Certain side effects would allow processing of remote node results to be 
considered last result
    * Local processing thread would be paused/non active and miss opportunity 
to write exception
    * This would manifest as incomplete results instead of a retry
