This will not happen during normal operation... The hcitool opens an
HCI_USER socket, which bypasses all of the kernel based MGMT control,
and gives the user space tool direct control over the controller, and
taking it offline for any shared usage. It therefore does not have the
race conditions that were inherent in MGMT when used by multiple user
threads. We therefore left the hci_request mechanism in place (in
hci_core.c) to issue the HCI commands from the hcitool.
