[MC-39034] World Save hangs game in Linux

(none of this will work in Windows, i have even tried with the same version on another computer that is the exact same model, except running windows)
1. Start a game (doesnt matter, creative or survival)
2. Every so often, the game will hang for around 10 seconds (confirmed in Linux, but not on windows on the same model of computer).
*important note: the hang is the same length of time each time, indicating a bug

Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report ([minecraft|http://hopper.minecraft.net/help/finding-minecraft-data-folder]/crash-reports/crash-<DATE>-client.txt) here.

Please attach the complete output of the "Development console" tab of the launcher.

Click the text, press CTRL-A to select all, then CTRL-C to copy, and CTRL-V to paste in a comment on this ticket.

If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".

If it is freezing over a certain period, there is a strong likelihood this is caused by your graphics drivers. You should try installing the most recent proprietary drivers from AMD.

Eleuin Development 2013-11-05T16:17:39Z

sadly, it is not my driver. i just updated my entire computer just this morning, and that includes browsers, games, runtimes, codecs, DRIVERS, and the main kernel. and its not that its freezing every so often (its mostly random when it happens), its that the game randomly freezes for around 10 seconds (its freezes for the same time period every time). and previous versions do work (in exception for those snapshots that didn't work period on linux)

As Kumasasa requested, it would be helpful if you included your console output.

Eleuin Development 2013-11-05T16:41:44Z

console output. seems like its in the world saving, and not the actual rendering

CubeTheThird 2013-11-05T16:54:00Z

Looks like it might be when your game is being saved.

Eleuin Development 2013-11-05T16:59:11Z

thats what the console output is saying. its just weird because this never happened before 1.7

CubeTheThird 2013-11-05T17:11:56Z

Have you been using any mods (eg optifine) in the past?

Eleuin Development 2013-11-05T17:40:22Z

not since 1.4 on a completely different OS install
