   Any news here? Can I do anything to get this fix in?

IIUC, the second iteration achieves the same goals as the first
one (i.e., reducing unnecessary allocation by refining the heap
monitoring machinery).  Is that correct?  (What am i missing?)

I would be happy to commit the second patch, if you could refine
it to add the extensive explanation of the first.  (You could
even mention the first approach, as an interesting but misguided
dead end.)  That way, we have a full record.

I would be extremely happy to commit a test along w/ the change,
if we can figure that out.  But it's not critical (we can do it

Re testing, i don't know how to go about setting up a test to
