But isn't this just reducing the likelihood of hitting the problem? Without
understanding why the entry limit gets exceeded (and fixing that), the
potential for this to happen again is still there.
Of course, the change made here has its own benefits, so I fully agree
it should be applied (though I wonder whether it's indeed a -stable
candidate).
