Description:
The sentence in commit_siblings "A larger value makes it more probable that
at least one other transaction will become ready to commit during the delay
interval." seems to belong in commit_delay instead.
That sentence in that location is correct. See “birthday paradox”.
Maybe phrasing it in the negative will make things clear - the more required sessions needed before allowing a delay the less likely the delay will be wasted.
