+BUGS:
+    * somehow the stamps or the make build cache gets confused.
+      Reproduce this by calling rebuild on a bbfile twice.
+      1st, some tasks are called twice (do_fetch for instance),
+      2nd, no tasks are called anymore on the second rebuild.
+      Obviously executeOneBB is corrupting some state variables
+      or making some bogus assumptions about state and/or control flow
