The buddy system is pretty gross for what we want. You don't need
to pull gross hacks with page tables or use complex algorithms
to handle memory allocation though!
I've been working on improved page allocation and kmalloc that
doesn't have nasty power-of-two limits, doesn't thrash any more
than necessary and is optimised for the common case. It's a slow
job because at this stage each little change needs careful thought
and a couple of hours benchmarking to see what effect it has. We are
talking a few microseconds variation but this code is called a lot.
