	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).
