coinitService implicitly required that runtime.LockOSThread() was called before (because ole.CoInitializeEx requires that all later calls happen on the same thread). This was true for one location that called coinitService, but not for another, causing WMI failures if the go runtime moved the go routine to another thread during the WMI calls. To fix this, explicitly call runtime.LockOSThread() in coinitService and runtime.UnlockOSThread() in the cleanup.
