Multiple persistent child-process-related test failures on Windows when running as a Service about node

Since I don't have a clue about this I'm just gonna be the rubber duck instead.

So the only difference here is how you launch Jenkins? Have you tried experimenting changing which user is running the service?

One difference I see is which hudson .bat file is being run:

Build 49

[node-forward-rackspace-iad-win2012r2-msvs2013] $ cmd /c call C:\Windows\TEMP\hudson8301516808398704284.bat

Build 50

[node-forward-rackspace-iad-win2012r2-msvs2013] $ cmd /c call C:\Users\ADMINI~1\AppData\Local\Temp\2\hudson2421968505119472450.bat

@ralphtheninja I did consider permissions as a possible cause here but dismissed it because "why would a permissions problem manifest only in a few child process cases like sleep 1 taking 50 seconds?".

Shame on me for thinking that way, this is Windows after all! A bit of googling yielded this:

I had this same exact problem executing a .bat file which in turn made a call to git.cmd using Process.Start from a windows service. The git command would execute immediately if the .bat file was ran directly from the command line, but would delay exactly 50 seconds any time it was called from the windows service.

Again:

So, here's Jenkins being run explicitly as Administrator: https://jenkins-node-forward.nodesource.com/job/iojs+v0.12+multi/nodes=node-forward-rackspace-iad-win2012r2-msvs2013/lastBuild/console

And, also the first proper SUCCESS! #18 is still going to cause some problems but this is real progress!

(edit by @mmarchini: was testing something on nodejs/node-auto-test, but it seems like the bot always comments on this repository when a Jenkins PR Job starts. Sorry for the noise)
