Description Simon Fraser (smfr) 2014-07-07 10:53:11 PDT 
WebLayer's -display looks like:

- (void)display
{
#if PLATFORM(IOS)
    if (pthread_main_np())
        WebThreadLock();
#endif

and this is necessary since this as a place where CA calls back into WebKit.

This lock is missing in the WebGL -display implementation.
