This module allow to return 204 or 444 code for some locations on low
memory condition:

http {
    degradation  sbrk=500m;

    server {

       location /some {
           degrade  204;

Currently it can be used if sbrk(0) syscall reports real memory volume
allocated by a proccess. It does not work for Linux and FreeBSD 7.0+ where
malloc() may use mmap(). It can be used on FreeBSD before 7.0 and on 7.0+
