Thereby, the meta-data to manage signal contexts in a signal receiver exceed the session's quota. As a consequence, the core thread calls env()->parent()->upgrade(...), whereby core's simple environment doesn't support resource upgrades. As a consequence the system crashes with just a few threads running in the system."}}
