Description of change

Refs: #2253 (comment)
Fixes: #6716

cc @bmeck & @mhdawson

Maybe we should be changing this to only skip the stdin part of the test? It seems like that is the bit causing issues?

CI: https://ci.nodejs.org/job/node-test-pull-request/2609/

[mhdawson]

Is this going to be excluded on centos (which I also saw failing in the ci) as well ? Just want to understand if excluding or trying to fix is the right thing to do ?

[Fishrock123]

@mhdawson can you point me to a failure?

[Fishrock123]

Looks like Centos did also fail here:

# # assert.js:90
# throw new assert.AssertionError({
# ^
# AssertionError: '' == 'A\nhello\n'
# at ChildProcess.<anonymous> (/home/iojs/build/workspace/node-test-commit-linux/nodes/centos7-64/test/parallel/test-preload.js:86:10)
# at emitTwo (events.js:106:13)

Looks like @santigimeno has an idea in #6716 (comment)

Hopeful fix from @santigimeno's idea/comment: #6722

EDIT: Whoops, fixed the link.

[Fishrock123]

@Trott that links to nothing?

Closing in favor of #6728
