+Subject: [PATCH] Increase Light Queue Size
+
+Wiz mentioned that large WorldEdit operations cause light to run on
+main thread. The queue was small, set to 5.. this bumps it to 20
+but makes it configurable per-world.
+
+The main risk of increasing this higher is during shutdown, some
+queued light updates may be lost because mojang did not flush the
+light engine on shutdown...
+
+The queue size only puts a cap on max loss, doesn't solve that problem.
