Will do.

I fixed a deadlock issue a few months back (CALCITE-874) but it's
entirely possible I missed something, and I do see intermittent hangs
in Travis-CI. Josh, can you please log a JIRA case with the stack?
It's not critical for this release.

Thanks for the pointer, Vladimir. I haven't dug into this corner of the code
yet, so I wasn't really sure what the guarantees on concurrency were meant
to be.
I plan to focus on the other issues from yesterday, but will try to swing
around to this after. Anyone else who has cycles/motivation should feel free
to look :)

As far as I can see, the problem is "non-properly-synchronized"
HashMap in ReflectiveRelMetadataProvider.
The fix would probably be to using ConcurrentHashMap there, however it
is better to doublecheck if there are more high-level data races
there.
