benchmark(title, log_level = Logger::DEBUG, use_silence = true) {|| ...}

Log and benchmark the workings of a single block and silence whatever logging that may have happened inside it (unless use_silence is set to false).

The benchmark is only recorded if the current level of the logger matches the log_level, which makes it easy to include benchmarking statements in production software that will remain inexpensive because the benchmark will only be conducted if the log level is low enough.

26:       def benchmark(title, log_level = Logger::DEBUG, use_silence = true)
27:         if logger && logger.level == log_level
28:           result = nil
29:           seconds = Benchmark.realtime { result = use_silence ? silence { yield } : yield }
30:           logger.add(log_level, "#{title} (#{'%.5f' % seconds})")
31:           result
32:         else
33:           yield
34:         end
35:       end
silence() {|| ...}

Silences the logger for the duration of the block.
