parking_lot has actually been considered for inclusion in libstd[0], as a better alternative to the native mutex implementation (parking_lot mutex are smaller, can be const-initialized, can be moved, and tend to perform better - all while not depending on external, non-rust code). The effort is currently on hold, but it's possible that it will resume in the future.
