Marcelo saw a 30% speed increase from 2.4.4 to 2.4.5pre3
on several tests.

At the moment the main issues left seem to be:
- balancing the inode + dentry caches versus the rest of
the memory users (I'm working on it now)
- simplifying __alloc_pages() a bit (I've got some things
ready but I'm waiting for some other people who say they
also have some stuff to add)
- making sure we get rid of all the highmem flushing
deadlocks ... there may still be a few around (ben, marcelo?)


Virtual memory is like a game you can't win;
However, without VM there's truly nothing to lose...
