    Bug 791424 - multithreading slows down color to grey
    
    After the last commit, reenabling multithreading for c2g makes it
    notably faster when GEGL_THREADS>1 (however, it only brings it on-
    par to GEGL_THREADS=1.)
    
    This reverts commit 58fcebb96505459c9aa29f910f04315d988e9c0c.
