Keyed Join fix for the remote handling of parts from othr clusters
When a smaller Thor was reading a file from a larger Thor where the larger Thor file overlapped, some slaves on the smaller cluster could find non-primary copies of the file locally. The effect of this was that other slaves would send requests to those local slaves, but did not map to the correct (non-primary) copy, resulting in a 'Failed to open' file error.
A workaround is to add this option:
which forces all KJ part thread handlers to access the keyed parts directly.
