# NOTE(akurilin): We are not going to add `eventlet` to `oslo.db` in
# requirements (`requirements.txt` and `test-requirements.txt`) due to
# the following reasons:
# - supporting of eventlet's thread pooling is totally optional;
# - we don't need to test `tpool.Proxy` functionality itself,
# because it's a tool from the third party library;
# - `eventlet` would prevent us from running unit tests on Python 3.x
# versions, because it doesn't support them yet.
#
# As we don't test `tpool.Proxy`, we can safely mock it in tests.
