another option would be to hack the sources directly. In the file 
"engine/SCons/Taskmaster.py" there already exists a check function named 
"_validate_pending_children" for debugging. It's prepared to be called 
in the method " _find_next_ready_node" twice, ll. 775 and ll.920. 
Uncomment those places, run your build and see what happens...
