The fact that the description of the lock is "<NSRecursiveLock: 0x16c2340> '(null)'" makes me suspect that you're synchronizing on a nil pointer, i.e. that when you call
	@synchronized(foo) { ... }
the value of foo is nil. I'm pretty sure that's illegal, and I would have thought it would throw an exception, but maybe not. Try putting a check above the block, something like
	NSAssert(foo!=nil, @"no foo");
