== degradation ==

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

<geshi lang="nginx">
http {
degradation sbrk=500m;

server {

location /some {
degrade 204;
}
</geshi>

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+
if MALLOC_OPTIONS=Dm.
