I just ran the same application again. The combined JS files are:
maps.gstatic.com/cat_js/intl/en_us/mapfiles/api-3/4/4a/
{common,util}.js
maps.gstatic.com/cat_js/intl/en_us/mapfiles/api-3/4/4a/
{map,overlay}.js
maps.gstatic.com/cat_js/intl/en_us/mapfiles/api-3/4/4a/{onion}.js
maps.gstatic.com/cat_js/intl/en_us/mapfiles/api-3/4/4a/{controls}.js
maps.gstatic.com/cat_js/intl/en_us/mapfiles/api-3/4/4a/{stats}.js
maps.gstatic.com/cat_js/intl/en_us/mapfiles/api-3/4/4a/{marker}.js
The grouping seems to be totally arbitrary. The chances of a cache
hit are very slim. I guess if I run it enough times, I will have
enough permutations in my browser cache to stumble upon a previously
cached file.
