The problem is that I personally don't see that issue at all. I even
installed 4GB of RAM to my development machine last year to be able to
reproduce this, but I can't, even when the memory allocator is under
heavy load. The only people who see this effect are Pedro Ribeiro and
William Light (both in Cc:), and both have been very helpful in trying
patches and reporting back in detail. Which instructions could we
probably give to these people to finally hunt this issue down?
