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*. -- Jason R.
