Steps to reproduce:

1. Create a new customized world with this preset:

{"coordinateScale":6000.0,"heightScale":684.412,"lowerLimitScale":2007.6409,"upperLimitScale":2007.6409,"depthNoiseScaleX":200.0,"depthNoiseScaleZ":200.0,"depthNoiseScaleExponent":20.0,"mainNoiseScaleX":5000.0,"mainNoiseScaleY":2570.9084,"mainNoiseScaleZ":5000.0,"baseSize":18.239437,"stretchY":4.2345076,"biomeDepthWeight":10.098592,"biomeDepthOffset":0.0,"biomeScaleWeight":10.098592,"biomeScaleOffset":0.0,"seaLevel":63,"useCaves":true,"useDungeons":true,"dungeonChance":8,"useStrongholds":true,"useVillages":true,"useMineShafts":true,"useTemples":true,"useRavines":true,"useWaterLakes":true,"waterLakeChance":4,"useLavaLakes":true,"lavaLakeChance":80,"useLavaOceans":false,"fixedBiome":-1,"biomeSize":4,"riverSize":4,"dirtSize":33,"dirtCount":10,"dirtMinHeight":0,"dirtMaxHeight":256,"gravelSize":33,"gravelCount":8,"gravelMinHeight":0,"gravelMaxHeight":256,"graniteSize":33,"graniteCount":10,"graniteMinHeight":0,"graniteMaxHeight":80,"dioriteSize":33,"dioriteCount":10,"dioriteMinHeight":0,"dioriteMaxHeight":80,"andesiteSize":33,"andesiteCount":10,"andesiteMinHeight":0,"andesiteMaxHeight":80,"coalSize":17,"coalCount":20,"coalMinHeight":0,"coalMaxHeight":128,"ironSize":9,"ironCount":20,"ironMinHeight":0,"ironMaxHeight":64,"goldSize":9,"goldCount":2,"goldMinHeight":0,"goldMaxHeight":32,"redstoneSize":8,"redstoneCount":8,"redstoneMinHeight":0,"redstoneMaxHeight":16,"diamondSize":8,"diamondCount":1,"diamondMinHeight":0,"diamondMaxHeight":16,"lapisSize":7,"lapisCount":1,"lapisCenterHeight":16,"lapisSpread":16}

2. When in the world, with console open, type /debug start.

3. Start flying around (loading new chunks). Notice the spam in console. See debug profile attached.

Confirmed in OS X. If this issue is closed, it needs to be reopened. This is a reproducible problem.

Has this happened more than once? Does it happen every time you close a world, or only with a specific world?
