Agreed. The ability to reserve some memory space for root processes is the
minimum requirement for being able to implement a recovery strategy in _user_
_space_. Therefore it must be right.

You can run non-vital daemons as bin or daemon. You can log in as root and
kill them.

Reserving 5% or 1M, whichever is least, would seem to be the best default
strategy. Low memory machines could disable the reserve.

PS - this brings up the question of whether one should be able to quota
memory space as well as disk space. Probably. Requests for more memory
are relatively infrequent.
