This commit fixes an issue where multithreaded applications lock up when they use both OpenGL and X11. This is being hit with a number of popular games on both quantal and precise. [TESTCASE 1 - No wine required] 1) download https://bugs.freedesktop.org/attachment.cgi?id=67051 2) compile and run: --- gcc -o test t.c -lxcb -lpthread; ./test 3) When broken (without the patch) you'll just see "o" repeating over and over, when working properly (with the patch) you'll see both "o" and "x" appearing in the output. [TESTCASE 2 - Wine required] 1) download http://bugs.winehq.org/attachment.cgi?id=41417 and extract it 2) run wine graphics.exe and watch for it to get hung. - 3) It should fade out or be hung on a green screen soon after launch without the fix. + 3) It should fade out or be hung on a green screen soon after launch without the fix.
