Here recompiling has to mean "destruct and compile" for D and B, and
"compile without destructing" for A.

If you don't recompile B, A would still inherit the old D through the
unchanged B.  However, the kernel library will automatically destruct
and compile B in this situation.  Thus, if you only wanted to make a
change to D, you only need to destruct D and then recompile A -- the
kernel library will automatically make sure that D is compiled, and
that B is destructed and compiled, during the recompilation of A.

If you destruct and compile B, and then destruct and compile D, B will
still inherit the old issue of D.  However, for the reasons outlined
above, B will be automatically destructed and compiled once more in this
situation.
