+===== Shutdown protocol =====
+When Minix is shutting down PM broadcast a KILL signal to all processes. That is not the best way to do it as it is racy and requires many asynchronous messages between PM and VFS
+The goal of this project is:
+  * separate killing POSIX processes from the rest of the system
+  * shut down system processes in the right order, e.g. filesystems before the disk drivers and not the otherway around
+  * remove the requirement of buffering of many asynchronous messages
+This change should make the shutdown always consistent and deadlock free.
