Is this still a problem in the latest release?

> seems like a build for a dependent module is triggered each time a dependency is built. This seems to cause modules several levels down in the dependency graph to be built many times for the same change in a root module (propagated once for each intermediate dependency relation). A module should not be added to the build queue if it already is in the build queue. 
> Also, if scm timestamps are propagated through the builds (seperate jira issue), it would easily be confirmed that the dependent module already is in the build queue with the same timestamp, and that one build of the module would be sufficient. Today it would be several builds, each from head with a few minutes between, with modules near the end of the dependency chain being built often and against different scm timestamps than the intermediate modules.
