---------------------------------------------
> Is this a problem regardless of whether it's a test or real code?
Yes - but this was not introduced by ZK-1355, the address resolution was always
there just wasn't tested. I'm guessing you'll see delays if you provide the
real client with non-existent addresses like I do in the test.
I just noticed that I already have a separate constructor for
StaticHostProvider that is invoked from the test, so I can make it avoid
resolution of addresses when running the test. I wanted to avoid doing this
earlier because its nice that both constructors use resolveAndShuffle so we're
actually testing the deployed code.

I didn't see this problem on my Mac but I do see it on Linux. Perhaps it has
something to do with this ?

> StaticHostProviderTest method testUpdateClientMigrateOrNot hangs forever.
> On my laptop getHostName for 10.10.10.* takes 5+ seconds per call. As a
> result this method effectively runs forever.
> Every time I run this test it hangs. Consistent.
