The issue is what Microsoft considers a process.
To Quote MS:

Note
* A script is not equivalent to a process. Instead, each script runs in an instance of the scripting host process; each time you run a VBScript script, an instance of either Wscript.exe or Cscript.exe is started. If you start five scripts, the Task Manager lists five instances of Wscript.exe. It does not list the names of the individual scripts running in each of these processes.

I know this is an issue with Java as well and I do believe there is a hack for java. (I think you end up recompling the JRE to get around this, by adding renaming code to the JRE, But I am not certain)

So your choices are a Major hack or doing as the frist responce said.
