Cron queue gets processed every time cron is called, regardless of whether it's already being processed elsewhere

This looks like a bug although maybe I'm just not understanding something.

If you look at drupal_cron_run() it has lock functionality which prevents more than one cron process from running at once.

However, the code which processes queue items during cron lives outside of that lock, and thus queue items will be processed every single time cron is called.

This could be an issue especially when combined with the "poormanscron" feature in core. For example, when one (unlucky) person triggers the cron process and gets a slow page request, then before it's complete everyone else who happens to visit the site during that time period seems like they will trigger the processing of queue items (even if they don't trigger the full cron processing) and therefore they might all get slow page requests too..
