webgl/conformance/extensions/khr-parallel-shader-compile.html

Updated in r274711, timing out in GLIB since, even with [ Slow ].

Checking the first loop of the test (~120), it seems the compile operations are not being offloaded to another thread, as there is a big wait in the compileShader calls. In the 7th iteration of the loop:

extraCode size 2949120
shaderSource(vertexSource) took 18ms
shaderSource(fragmentSource) took 17ms
compileShader(vs) took 1460ms
compileShader(fs) took 1392ms
linkProgram(program) took 1ms

This is causing the measuredCompileDuration to always be smaller than the threshold (500ms), as it's actually just a get operation, and the code never triggers the loop exit condition.
