Detailed Description

The KisUpgradeToWriteLocker class is use for RAII style unlocking the read lock and then locking the lock for write. We basically "upgrade" the lock to a write one.

WARNING: during the upgrade the lock passes the "unlocked" state, so all the protected data you acquired during the "read" phase might have become invalidated!
