A python package that provides useful locks.

It includes the following.

- Locking decorator

    Helpful locked decorator (that acquires instance objects lock(s) and
    acquires on method entry and releases on method exit).

- Reader-writer locks

    Multiple readers (at the same time).
    Single writers (blocking any readers).
    Helpful read_locked and write_locked decorators.

- Inter-process locks

    Single writer using file based locking (these automatically release on
    process exit, even if __release__ or __exit__ is never called).
    Helpful interprocess_locked decorator.

- Generic helpers

    A try_lock helper context manager that will attempt to acquire a given
    lock and provide back whether the attempt passed or failed (if it passes, then
    further code in the context manager will be ran with the lock acquired).
