+Subject: [PATCH] Synchronize PalettedContainer instead of
+ ThreadingDetector/Semaphore
 
 Mojang has flaws in their logic about chunks being concurrently
 wrote to. So we constantly see crashes around multiple threads writing.
 
 Additionally, java has optimized synchronization so well that its
-in many times faster than trying to manage read wrote locks for low
+in many times faster than trying to manage read write locks for low
 contention situations.
 
 And this is extremely a low contention situation.
