Ah, OK.  That is indeed a fix for an important bug.  Not knowing the mm
code very well, I'm not in a position to judge whether it's safe enough
for a -stable stream or not.  If it is and it could be done safely
without relying on 3/4, that would seem safer to me, but it is not a
strong opinion.


Thanks,
Roland
