What about the AIX way? When the system is nearly OOM it sends a
SIG_DANGER signal to all processes. Those that handle the signal are not
initial targets for OOM... Also in the SIG_DANGER processing they can take
there own actions to reduce their memory usage... (we would have to look out
for a SIG_DANGER handler that had a memory leak though)
