function killExtraIEProcess can't work

[LinZhicheng]

Windows Server 2012 R2
IE 11

I use karma to run QUnit test in the Jenkins CI build by execute cmd script, but after IE started, it always disconnected because of timeout.

I found in Task Manager that there are two IE process, one is 32bit and the other is 64bit. In the source code, I found you wrote the function killExtraIEProcess, I guess it may not work as expected.

Meanwhile, when I inputted the command in cmd manually, it worked very well. I'm very confused, hopefully you have some solutions.
