73f9db47ae5a1a9fa29a98dfe92d557ad51234c3 without
modification.
This introduces a number of code style violations. The file
already has the magic words to skip test-check-code.t. I'll
make additional changes to clean up the test-check-py3-compat.t
warnings and to change some behavior in the code that isn't
suitable for general use.
test-check-commit.t also complains about numerous things. But
there's nothing we can do if we're importing as-is.
# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
