Lazy Cron delaying page render

[statestreet]

I have a slow background sync function that has to hit a web service a bunch of times (unfortunately there appears to be no way to consolidate the API requests) that I've bound to a Lazy Cron hook. However, it appears that I've somehow caused Lazy Cron to run before `ProcessPageView::finished()` as opposed to after. Every time the Lazy Cron is scheduled to fire, it takes 30 seconds to render the page.

Any ideas what I might be doing wrong?

I do not see any accidental way this could happen. Maybe there is another ProcessPageView being finished? The only thing I could think of is a FormBuilder form in an iframe at the top of a page or something like that.

Weird. I can't think of any reason another page would be rendered (no iframes, no additional render() calls). I threw an echo into the background sync function, and indeed, it shows up at the end of the page.
