Public bug reported:

I'm still not happy with cancellation. The thumbnailer handles
cancellation correctly, that is, successfully cancels anything that
hasn't been sent via dbus yet. But it doesn't work well at the UI level.
When thumbnailing a large collection of MP3s without artwork and
scrolling forward quickly, the requests that are scrolling off the top
of the screen are not physically cancelled, so it takes a long time for
the thumbnails for the visible section of the list to show up. In
addition, more often than not, the application times out and shows "no
artwork" images.

Ideally, I'd like to see whatever is in the currently visible section to
get priority.

Need to investigate what exactly is going on here and whether there
might be a way to mitigate the issue.
