Well, the proc server registers for these notifications. I'll add
this RPC to the process protocol:
/* Create a new task namespace. PROCESS claims the responsibility to
manage all tasks in this namespace. Any task created in this
namespace will automatically be declared a child of PROCESS, and a
`mach_notify_new_task' message is sent to NOTIFY. If PROCESS dies,
the proc server will terminate all tasks in the namespace. */
routine proc_make_task_namespace (
process: process_t;
notify: mach_port_send_t);
`boot' will use this call to create a task namespace, and from that
point on the proc server will relay the notifications for all tasks in
that namespace to `boot', which will keep a list of these task ports
so that it can implement `S_processor_set_tasks'.
