 Actually the opposite would be worse when a page with the AJAX js is
 cached.

 > More recent posts are a different matter of course -- you wouldn't want
 an ajax call around when your site's on Digg.

 Exactly, will have to add the AJAX only on posts that are couple of days
 old.

 priority 1...

 Yes, in theory the browser should display the page before calling wp-cron.
 However while testing that wasn't always the case. The test: added 5
 seconds delay to wp-cron and ran it constantly. While accessing the site
 with two browsers concurrently, one would wait for 5 sec. sometimes before
 showing the post.

 Think that has been tried before too but didn't make it into core.
