By default, the standard library log package outputs to stderr.
However, stderr is redirected through a pipe to the Android logger,
so recent writes may be not have been sent when os.Exit is called.
The log.Fatal family of functions does just that: write to the log
and call os.Exit.
To ensure all messages are sent, register a synchronized logger at
startup.
