Example:
Cluster C2 is dependent on cluster C1. Module M1
is in cluster C1 and module M2 is in cluster C2.
And finally M1 is dependent on module M2 (cyclic
dependencies if you take account the cluster
dependencies).

When you run a build with such a dependencies,
those are not detected, the build runs (cycles the
cluster building) until it runs out of memory.

It would be nice such error cyclic dependencies
(cluster/modules) are detected and reported and
let the build failed at the beginning.

It would save a lot of time for detecting that
kind of issue.
