[Zope] winlock.error: 33 -- Zope2.app()

[mycrazylists mycrazylists]

Hi All,
       I am getting winlock.error :33 when trying to execute a function called connectZope (mentioned below). If i execute the same function when zope is not running, it works fine. I think this is bcoz of zope acquiring lock on data.fs when its running. Am i missing anything here or Is there any other way i can accomplish the same ( i wolud like to execute a python script (zope object)) from a background process instead of calling the same on the Web).   
Any help would be appreciated. 

def connectZope():
    from Zope2.Startup.run import configure
    configure('C:\Zope-Instance\etc\zope.conf')
    import Zope2
    app = Zope2.app()
    return app

app = connectZope()
app.myscript()
