Why would pathlib need to provide this when tempfile already does?
with tempfile.NamedTemporaryFile(prefix='') as f:
tmp = pathlib.Path(f.name)
with tempfile.TemporaryDirectoryDirectory(prefix='') as d:
tmp = pathlib.Path(d.name)

The current working directory is not "a resource" though it's a big
piece of global state. I've been bitten by
context-manager-unexpectedly-being-global-state in the past (with
warnings.catch_warnings, I had not noticed the note about
thread-safety). All in all, not a fan.
