It's been running for a while now, integrated in the 2.4 kernel. The way Linux manages to avoid the horrors you describe is by simply not letting the kernel use more than its 1GB (or 2GB) of KVA. No special tricks to make the kernel use more memory, let it go on a diet instead. > FWIW, on the "Linux has it, so FreeBSD should have it" > arguments: > > "If all your friends jumped off a cliff..." Fully agreed, but as long as you don't do any weird tricks trying to let the kernel itself use more memory, it's not at all like jumping from a cliff ...
