  The problem with binary format is, if the kernel changes, bang!
ps/top/systat/xosview are useless until you can upgrade userland.
I've already coded up changes to ps that allow it to fall back on
/proc when kvm isn't happy (if /proc is mounted, that is), so
it works great in practice.  :)

  Binary format can also be provided, for performance reasons, if
desired.  It just isn't as flexible, and won't be my main focus
at first.
