Server Interface - Inform bootstrap server that initialization is complete.
kern_return_t bootstrap_completed (mach_port_t bootstrap_port, task_t task);
This interface allows a given server task to inform the bootstrap server that it is fully initialized and ready to handle requests. Upon receiving such notification, the bootstrap server can initialize any additional servers that may require services provided by the previously initialized server.
Note the following: not all servers that may be invoked by the bootstrap server send this message upon startup. If the bootstrap server is told to wait for this message before spawning further servers (via setting a flag in the bootstrap.conf file) and the server just invoked never sends this message, the bootstrap server will wait forever.
Currently, this interface is used exclusively by the default pager server so that the bootstrap server can defer initializing the OS server until the default pager is in place. (In small memory configurations, an OS server may not be able to initialize successfully unless the default pager is ready to handle paging requests.)
