rwlock-py

A writer-biased Reader-Writer Lock

Forked from: http://code.activestate.com/recipes/577803-reader-writer-lock-with-priority-for-writers/

Original Author: Mateusz Kobos http://workshop.mkobos.com/

The enhancement based on original implementation

• Protect the critical section of writer-acquire and writer-release. Several writers waiting for readers to release the lock will get the lock in the order of arriving time.

Known issues

• Not able to query whether lock is in reader(s) or writer
• If the lock is released several times, there will be a problem
