You obviously didn't pay attention to Chris's posting, nor apparently did
you see th "embedded" in my posting.

Who said anything about even having disks to swap to?  I just want the
kernel to tell me when there aren't any more backing store resources
(including *PHYSICAL PAGES*) for the memory allocation I just requested
from userspace.  That way, my correctly written program can take appropriate
action (like, say, invoke its type-stable memory pool garbage collector, and
try again).

Right now, BSD doesn't do this, and that makes creating a truly reliable
system *very hard*.
