Get a real operating system ;-)

Seriously, the proposed patch introduces overhead into a place that is
already a known hot spot, in return for not much of anything.  It will
*not* bound backend memory use very accurately, because there is no way
to track raw malloc() calls.  And I think that 99% of users will not
find it useful.
