Yes, we saw symptoms like that, too, but if GRS contention resolution
is defined to be FIFO, then there is no race condition one system can
win.

I wanted to confirm I'm not missing something that changed in GRS
processing, before opening a PMR. Jim Mulder confirmed that it still
had to be FIFO. We now have to find out why we saw different behavior.
