title: why does this script not work with threading python
body: <p>so i've been trying to ifnd a way to access task manager.  I've tried a few methods including the wmi module and the windows tasklist but neither suit my need. wmi is way too slow and tasklist becomes too slow when i access it multiple times concurrently in something using multiprocessing.  so i found this script which works quite nicely but i can't get it to work with threading.  </p>
  
  <pre><code>import win32com.client
  strComputer = "."
  objWMIService = win32com.client.Dispatch("WbemScripting.SWbemLocator")
  objSWbemServices = objWMIService.ConnectServer(strComputer,"root\cimv2")
  colItems = objSWbemServices.ExecQuery("Select * from Win32_Process")
  for objItem in colItems:
     print "Name: ", objItem.Name
     print "File location: ", objItem.ExecutablePath
  </code></pre>
  
  <p>this is the error:</p>
