# Runs `loom` tests, using `cargo nextest` if it's available, or `cargo test`
# otherwise.
#
# Usage:
#    All environment variables honored by `loom` can be used to configure `loom`
#    test behavior. Default values are set for `LOOM_LOG` and
#    `LOOM_MAX_PREEMPTIONS`, if those variables are unset when the script is
#    invoked.
#
#    Any command-line arguments are passed through to the test invocation.
