    By default, this command will show which locks are held. This
    includes the user and process holding the lock, the amount of time
    the lock has been held, and the machine name where the process is
    running if it's not local.

    Locks protect the integrity of Mercurial's data, so should be
    treated with care. System crashes or other interruptions may cause
    locks to not be properly released, though Mercurial will usually
    detect and remove such stale locks automatically.

    However, detecting stale locks may not always be possible (for
    instance, on a shared filesystem). Removing locks may also be
    blocked by filesystem permissions.

    Returns 0 if no locks are held.
