... I don't want to miss the change to thank you, Robert, for the detailed explanation. I have backported b4fbe392f8ff6ff1a66b488eb7197eef9e1770a4 to 9.1.3 and it is working well in production for ~2 weeks, but I must admit that I had put in the unnecessary read barrier into SIGetDataEntries just to be on the safe side. I will take it out for the next builds.
