Thiago Macieira 0aedca2f97 Revert "Fix performance of recursive read-write locks"
This reverts commit 666486b3ef, which
removed the QHash that protected against reader recursion
deadlocks. Without this hash, a reader will block on
d->readerWait.wait() until the writer finishes its task. However, the
writer never starts because there's a reader that hasn't released the
lock. That's a deadlock.
