This claimed problem is not adequately described-- because I don't see it. Therefore there is something else going on here. I have 8 GB of memory on my Macbook Pro, and I've never seen anything like the problems described in this article. I leave my machine up for weeks at a time, I leave the Time Machine drive connected for weeks, and never have a slowdown, even when time machine is backing up. The only time I have memory issues is when I have too many safari tabs open for too long. Eventually safari takes too much memory. So, I shut down safari and start it back up-- it opens up all the tabs that were open and takes a lot less memory. I'm kinda astounded that people with 20 and 32GB of RAM and 8 CPUS are saying it takes 5 seconds to open a terminal window. Have never seen anything like that. I would venture to guess that these people who are seeing the problem are running a kernel extension or possibly have otherwise modified their machine.
