Be careful what you wish for, Jared Jared Jared. I don't think the
performance hit those already underpowered CPUs are going to take by
adopting virtual memory is going to help matters much.
Palm has taken an interesting approach to get rid of fragmentation: the
OS is allowed to move (some) structures from one physical memory
location to another. This only works if the processes that use this
memory are written to support this, of course.
(BTW, you'll experience very little fragmentation if you make sure your
box never comes close to running out of memory.)
