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.
