I think appcache handles this particular case reasonably well (modulo it's 
other known limitations, anyway). The caching progress can be easily 
reported to the user (either by the UA or the page), so the user can know 
that they should leave the tab open while it does the update, and yet the 
page is usable in the meantime.
