„ZRS(sTAn interprocess locking implementation.

    This is a lock implementation which allows multiple locks, working around
    issues like http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=632857 and
    does not require any cleanup. Since the lock is always held on a file
    descriptor rather than outside of the process, the lock gets dropped
    automatically if the process crashes, even if ``__exit__`` is not
    executed.

    There are no guarantees regarding usage by multiple threads in a
    single process here. This lock works only between processes.

    Note these locks are released when the descriptor is closed, so it's not
    safe to close the file descriptor while another thread holds the
    lock. Just opening and closing the lock file can break synchronization,
    so lock files must be accessed only using this abstraction.
