many GET requests for LivePage js modules

Greetings.  For an implementation like the following:

    class Index (rend.Page):
        addSlash = True
        docFactory = loaders.xmlfile (util.sibpath (__file__, 'index.html'))
        def child_main (self, ctx):
            return MainPage ()

    class MainPage (athena.LivePage):
        docFactory = loaders.xmlfile (util.sibpath (__file__,
'main_page.html'))
        addSlash = True

Every time MainPage is reloaded it triggers a wave of http GET requests.
For example:

    GET /main/
    GET /main/bfacf1d9079bfb07fc119574795e9ceb/jsmodule/MochiKit
    GET /main/bfacf1d9079bfb07fc119574795e9ceb/jsmodule/Divmod
    GET /main/bfacf1d9079bfb07fc119574795e9ceb/jsmodule/Divmod.Defer
    GET /main/bfacf1d9079bfb07fc119574795e9ceb/jsmodule/Divmod.Runtime
        ...

But the jsmodules above are static and not instance specific.  Is there a
way for those to be referred to more of like a root resource than child
resource?  Then they will not have be fetched across the net each time.

Thanks in advance for any insights,
