Hmmm, if that were true, that would actually sound like *worse* memory management to me... To a certain extent, you want as little "free" RAM as possible in OS X; the inactive category is for things that were once loaded into RAM, are no longer needed, but are still kept there in case they are needed again. This makes the computer faster because it requires less hard drive access. Of course, some things will never be used again; once the program is done with some data, it must be replaced from scratch rather than replaced from what it was when the program last finished. But since the speed of RAM is about 3 orders of magnitude greater than the speed of the hard drive, it's an optimization worth having.
