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.
Its not a new technique - if you allocate memory "handlers" rather than addresses and ask the OS/Memorymanager to lock a handler in memory (and give you an address) then the OS/MM is able to move around unlocked memory blocks, even on/off disk, at whim. Win16 memory allocation looked like this, and I'm sure it was lifted from something even older. Its not actually a bad idea in a single-process standalone application. It certainly beats using a VM in this instance. Anyway, back to the network topics. Adrian -- Adrian Chadd I'm only a fanboy if <adrian () creative net au> I emailed Wesley Crusher.
