Hmm. This is only used by the browser process but the code is in common. It
should be in a common jni registrar or you'd blow up calling it from the
renderer.

I don't want to create a common jni register only to delete it in a few days
time so I am leaving this until we decide whether we are moving
startup_metric_utils.*, and if so where to. Although it is architecturally wrong
none of these functions are actually ever called from the renderer, so it won't
actually blow up.
