The smart os has a timeout error. It seems not related. And the raspbian is so slowly.

LGTM but can I have one more LGTM from @nodejs/collaborators? Perhaps it would be good to have a regression test for this.

Shouldn't this be stderr then?

Or simply, console.error?

Add the regression test.

process._debugProcess(pid);
} catch (e) {
if (e.code === 'ESRCH') {
console.error('Target process: ' + pid + ' doesn\'t exist.');

We don't need to use escape \ enclosed by " or `.

console.error(`Target process: ${pid} doesn't exist.`);

Didn’t see template string be used in node core, so I don’t use it. If it’s recommend, I will replace it.

Yes, We can use template string literals. We switched closure-linter to eslint.

Here's another test run: https://jenkins-iojs.nodesource.com/view/iojs/job/iojs+any-pr+multi/772/ - the last one failed because of style issues in the test case...

When using `iojs debug -p <pid>` with an invalid pid, the debugger
printed an internal error message because it wasn't smart enough
to figure out that the target process didn't exist.  Now it is.
