Me too.  'Was just thinking of allocators which give back valid
but inaccessible memory for 0 bytes so that each access would
fault.  (As opposed to give back minimum allocation.  Or give back
minimum allocation but in debug mode "put canaries" so that write
accesses "are detected", but read ones not.  That mediocre stuff
that i was and am doing thus.  Whatever.)

Thanks, and a nice weekend.
