}

I'm curious wouldn't this have worked anyway? We've always buffered up events until load, and flushed them when loaded. Can you explain behavioral differences between the existing implementation and this one?

Can you add a note that this should only be called once? Want to make it clear that calling this with different settings won't essentially 'reload' analytics.
