Well, as I said, I'm testing with Yong Zhang's patch, and it seems to be
doing the trick, so I am actually not pushing for my patch right now.
But please stop characterizing this as "blindly increasing the limit",
because that is not at all what I or others do. We have a debug build with
tons of options turned on in which case we increased it to the minimum
that worked for us, and we have a tracing build in which case we left it
at the default. Also as I pointed out, in Sven's case it sounds like they may
have had a build where they even wanted to decrease it.
Your objection in the past was that it was another tunable that nobody understands, and I
have more sympathy for that argument. My counterargument is that if we're
all putting a version of this patch in our private builds, then it's a tad
counterproductive. Let's leave things the way they are for now, unless
this becomes a problem again.
