I am running process.stdin example from docs:

process.stdin.setEncoding('utf8');

process.stdin.on('readable', () => { const chunk = process.stdin.read(); if (chunk !== null) { process.stdout.write(data: ${chunk}); } });

process.stdin.on('end', () => { process.stdout.write('end'); });

I expect the same results as in node v9 and below: command line should wait for my input and return it prefixed with data: . Instead, process is closed right away. I believe this is regression as example works fine in node v9 and v8.
