Review Comment:
@cstamas Any suggestions about whether we should use separate executors for the Maven parallel build?

> h3. Background
> When building a project with dependencies not yet available in the local repository, I noticed that Maven 3.3.9/Aether 1.0.2 first downloads the dependency POMs _sequentially_ and then proceeds downloading the dependency JARs with up to 5 threads _in parallel_.
> Due to this, when first building a project with a large number of dependencies, downloading a large number of small POMs may take a lot longer than downloading the much larger JARs, or even longer than building the project itself, especially when a repository manager is used which increases the download latency.
> h3. Enhancement
> Download POMs of (transitive) dependencies in parallel to significantly speed up initial builds of large projects.
