No source file, test, or entry point is identified in the issue. Reproduce the Gmail sync behavior from Settings > Accounts > Google > account > Gmail and inspect the supplied logcat while tracing the sync implementation. Done means repeated syncs wait as expected instead of starting immediately again.
