# Since 1.67 we can't trust RUST_TEST_THREADS to do the right
# thing.  It runs multiple threads with a lock to only allow one
# to run at a time, which breaks Stakker single-threaded tests.
# See: https://github.com/rust-lang/cargo/issues/11896 and
# https://github.com/rust-lang/rust/issues/104053

# Usage: <command..> __ <features..>
