Thanks for this idea, it looks like a real step forward for my issue.

Yet, now that this works, I have found another problem.

If someone do

make a b e

the system build e before b is completed.  But e doesn`t detect b as
it has not been built before it...

So the sentinel make sure that e is built only after at least one of a
b c d is built but it doesn`t garantee that e is the last one built
which is also another need I have.
