ReaderWriterLock

A reader writer lock that allows

• taking locks READ_PREFERRING or WRITE_PREFERRING
• taking locks BLOCKING-ly or NON_BLOCKING-ly
• It allows you to downgrade writer lock to reader lock and upgrade reader lock to writer lock (second of which may fail).
• It allows you to have an external lock allowing you to build complex functionalities aroung this lock (see my projects Bufferpool and WALe).
