Detailed Description

Read XOR Write lock, "prefer read" variant

Allow either multiple reader or multiple writer. When a reader arrives, writers stop taking the usecount. The reader has access once all writer finish.

To stop writer from locking, the reader will CAS a very low value.

If max_writer is 1, this becomes rwlock, but with a priority on the reads
