* This uses a non-blocking $wgMemc lock to reserve the user name in question. This should prevent two threads from reaching LOCK IN SHARE MODE and getting stuck on INSERT. The lock is global to better cover auth plugins. * This adds a BagOStuff::getScopedLock() convenience method. It uses less queries than LockManager by being EX only. * Avoid extra lock attempt in lock() in non-blocking mode. * Removed (un)lock() HashBagOStuff overrides that made it behave differently than other caches (wrt to re-entrance). Bug: T106850 Change-Id: Iecf95206d712367f5d202f76ab0eaa9d7bdabf2b
