Thomas Van Lenten d6590d6534 Drop all use of OSSpinLock ... Apple engineers have pointed out that OSSpinLocks are vulnerable to live locking on iOS in cases of priority inversion: . http://mjtsai.com/blog/2015/12/16/osspinlock-is-unsafe/ . https://lists.swift.org/pipermail/swift-dev/Week-of-Mon-20151214/000372.html - Use a dispatch_semaphore_t within the extension registry. - Use a dispatch_semaphore_t for protecting autocreation within messages. - Drop the custom/internal GPBString class since we don't have really good numbers to judge the locking replacements and it isn't required. We can always bring it back with real data in the future.		2015-12-17 16:05:50 -05:00
