enforce time limit based on all the time that a site was in active
rotation, including time it spent waiting for its turn to be brozzled;
this undoes the change from b9640b8a30c934, because now it seems that
was the wrong decision (brozzler jobs with many seeds and low
max_claimed_sites hanging around forever)
like this one:
Uncaught DOMException: Blocked a frame with origin "https://www.youtube.com" from accessing a cross-origin frame.

not sure exactly why this happens but we just have to handle it
and bypass downloading metadata about individual videos as well as the
videos themselves (for youtube playlists), because even just the
metadata can take many minutes or hours in case of thousands of videos
because youtube-dl's can be annoyingly verbose, confusing, doesn't tell
us the things we're interested in, and doesn't tell us where the
messages originate
finish_frag_download, instead of locking around monkey-patching, to
allow different threads to youtube-dl concurrently, but still not
interfere with each other
because we expect to capture videos from individual watch pages, and
often processing thousands of videos with youtube-dl before the page is
ever opened in the browser is not desired behavior and is a crawling
problem
which was causing awfulness like this:

i.e. pushing the same stitched-up video to a bunch of wrong places :(
