Which makes more sense, continuing to maintain our library or fixing
that bug and maintaining pylockfile? How big is pylockfile compared to
what we have? Does it solve problems our existing locking code doesn't
solve (and that we care about)?

That makes sense. When I made the list of libraries to release this
time, I called them all "oslo.foo" because I wasn't digging into the
code deep enough to figure out whether they could be something else. I
expected the person managing the spec for the release to do that step,
but I may not have made that clear.

The main thing I would be concerned with about using a non-oslo name
for oslo.concurrency is whether or not it uses another oslo library
like oslo.config. If we can completely avoid those dependencies, then
it should be safe to release it under a name other than
oslo.concurrency.
