Yes. The most that an application can say concerning a shared resource is: "I am no longer interested in this resource and I will no longer pay for its residency". Whether to remove it is a more global question. If you frame the problem this way, you will rapidly conclude that the question of "sponsorship" is extremely complicated, and after a lot of literature search you will come to the conclusion that something like a futures market is needed, and that our meat-world understanding of how a futures market works actually isn't sufficient. It's a VERY hard and very open problem. shap _______________________________________________ L4-hurd mailing list [email protected] http://lists.gnu.org/mailman/listinfo/l4-hurd
