nop, this won't work. Because smsbox client *may* connect without
explicite ID and hence conn->boxc_id would be left == NULL.
So when a smsbox connection breaks, and the smsbox was not having an
smsbox-id then the mutex is tried to unlock and crash:
2003-08-25 11:45:05 [10] ERROR: Connection to box <127.0.0.1> broke.
2003-08-25 11:45:05 [10] PANIC: gwlib/thread.c:100: mutex_unlock_real:
Mutex failure! (Called from gw/bb_boxc.
c:199:boxc_receiver.)
