Class: RedisLockManager  - X-Ref

Manage locks using redis servers.

Version of LockManager based on using redis servers.
This is meant for multi-wiki systems that may share files.
All locks are non-blocking, which avoids deadlocks.

All lock requests for a resource, identified by a hash string, will map to one
bucket. Each bucket maps to one or several peer servers, each running redis.
A majority of peers must agree for a lock to be acquired.

This class requires Redis 2.6 as it makes use Lua scripts for fast atomic operations.
