   yet under the degrading gracefully subject, the VM should clearly make
the distinction between a valid high load and thrashing. The system should
not start any load control/ process penalization if what we're having is
a subtle (but perfectly valid) high load around.

   Formulating a little better (I guess):
   - there should be a clear definition of _what_ is a system degrading,
so we can actually try to do it gracefully.
