Huh? If you kill the X server, and all the memory is suddenly reclaimed,
it certainly is associated with the X server!
Just because a client exits, it doesn't mean that whatever memory the
X server allocated to deal with that client is freed!

I don't think this has anything to do with UVM or Mach VM. I think what
you're seeing can be completely attributed to userland code, specifically
the X server implementation.
