+Subject: [PATCH] Avoid issues with certain tasks not processing during sleep
+
+Execute processQueue tasks during sleep: needed for console tab completions, pre join event, etc.
+
+Upstream has set precedent that the bukkit scheduler will still tick during sleep, which avoids some problems
+with plugins not accounting for the new sleep feature, but can still lead to others. Because of this we have disabled
+sleep by default, which avoids the problem and makes it more obvious to check if this is the cause of issues when
+enabled. We also unload chunks during sleep to prevent memory leaks caused by plugin chunk loads.
