implements Closeable

Programming model with this class:

 
 try ( CommandlineExecutor exec = new CommandlineExecutor( cli, endOfStreamsCountdown );
       CommandlineStreams streams = exec.execute() )
 {
     // register exec in the shutdown hook to destroy pending process

     // register streams in the shutdown hook to close all three streams

     ReadableByteChannel stdOut = streams.getStdOutChannel();
     ReadableByteChannel stdErr = streams.getStdErrChannel();
     WritableByteChannel stdIn = streams.getStdInChannel();
     // lineConsumerThread = new LineConsumerThread( ..., stdErr, ..., endOfStreamsCountdown );
     // lineConsumerThread.start();

     // stdIn.write( ... );

     int exitCode = exec.awaitExit();
     // process exitCode
 }
 catch ( InterruptedException e )
