Function shared_open_file_request 

pub fn shared_open_file_request(
    control: OpenFileControl,
) -> (DetTime, MmId, GlobalRequest)

The global request that carries one shared open file control message. It is answered before any clock accounting, so its clock and address-space fields are placeholders. The sender is the thread the backend’s transport names for the request; for in-guest LiteInst that is the runtime’s own envelope, checked against the connecting process at admission, on a connection the guest cannot write to.
