Since you've said that after deleting the file, the loading time does not
reduce, I'd say that the problem is not in the file.
Have you tried to not include the file in the HTML pages? Does the load
time change?

I've had a similar problem. If I include a non existent file, webkit will
still try to load it. The document ready event (or whatever the name was)
would not fire, until the file is loaded, or it times out (I think it was
about 40 seconds).
