I'm talking about a "blip" being a single allocation.  It's *LITERALLY*
the smallest (aka. lowest) possible quantum of memory pressure.

So go ahead and try to write the changelog without "high" or "low".
But, sheesh, if you and are somehow using "high" and "low" to describe
the exact same condition, I think that's a rather large communication or
understanding problem somewhere.  It doesn't bode well for this simple
patch.
