A python package that provides useful locks.

It includes the following.

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

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

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

• 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).
