+SYNOPSIS
+ string get_bb_uid(void)
+
+DESCRIPTION
+ Is called to get the ``backbone id''. Objects whose creator is
+ the backbone id are ``trusted'', and will automagically get
+ the uid and euid of the object that caused to load or clone
+ them.
+
+ The backbone id is also temporary given to objects while being
+ called via process_string().
+
+HISTORY
+ Since 3.2.1, get_bb_uid() is needed just for process_string()
+ if no this_object() is present.
