@michael-o can you please specify what changes are requested with your
"change request" PR review? It is unclear to me. As for me, this PR is good to
merge (and probably improve it later re shared executor, but is def out of
scope for this PR)

> 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.
