Actually, I was thinking about the possibility to extend setrlimit semantics to support this. i.e. an extra parameter which would indicate that we want to be notified (via the return value) that our contract request could not be fulfilled. Using this extra parameter would modify's the kernel's behaviour in that the kernel will "agree" to preserver this process as much as possible in case of resource starvation (that's the main difference with setrlimit).
