It does for some people, but leads to active file corruption for others. The cause has yet to be tracked down, as the VM guru (John Dyson) can't seem to replicate the behaviour causing corruption on his system(s). My current guess is that if your machine doesn't swap/page while running the sharedactive patch, you'll be okay, but don't quote me on that, and don't blame me if it doesn't work!
