Hi [~ehiggs], thanks for posting the new patch. Quick question – can we move
the refactoring of {{TestInMemoryLevelDBAliasMapClient}} to a different JIRA?
It doesn't have to be a part of this one.{quote}
Done. I kept the fix where we use NetUtils to find an available port to make
sure tests are more robust.

obscures the patch intent and makes it more difficult to review than it needs
to be.

> Otherwise the BlockAliasMap will grow indefinitely(!).
