I think more EINSUFFICIENTCOMMENTS. The patch should also add a comment
to the function, along the lines of "While we have the lock, also update
RecentGlobalXmin, so that we will have as up-to-date a value as possible
for next time". You've also failed to document the meaning or purpose
of the added output parameter.
