To elaborate on that:

1) there already is lots of policy in the kernel (scheduler,
   page stealing code, users can nice-down-but-not-up, ...)
2) thrashing and OOM are relatively rare situations
3) I can see absolutely no reason why you would ever want
   to take a 2 kB piece of code from the kernel and put it
   in a 32 kB userland daemon (which would need another 32 kB
   of kernel overhead for task struct, pagetables, etc..)
