ENOTCONN thrown when calling process.stdin.end() in node 10.1.0

Hi all,

If I run this file:

process.stdin.end();

using node 10.1.0, 10.9.0 or 10.10.0, it throws an ENOTCONN error.

This is the output when using node 10.1.0:

cbm test $ node index.js
events.js:167
 throw er; // Unhandled 'error' event
 ^

Error: shutdown ENOTCONN

But when using node 10.0.0, no error is thrown.

Is that a bug?

It may seem useless, but I'm actually trying to solve this bug for code that looks more like this:

try {
 process.stdin.pipe(process.stdout);
 setTimeout(() => {
 process.stdin.end();
 }, 2000);
} catch (error) {
 console.log('ERROR:');
 console.log(error);
}

So the code I'm working on uses process.stdin.end(); to finish the program. It indeed finishes, but only after throwing the error. By the way (and I don't know if it has something to do with this issue), if I use process.stdin.destroy(); instead of process.stdin.end();, it works as expected.
