This is because we need to initialize the gbm_device for the DRMDeviceNode being used in the main thread. There is already a call do DRMDeviceManager::initializeMainDevice(...) inside GPUProcess::initializeGPUProcess(), but that does not initialize the gbm_device for the DRM render node, which then we attempt to lazily initialize from one of the WebGL worker threads.
