Currently, if wikitext can not be rendered within the time limit of 60 seconds, an error message is displayed (WMFTimeoutException). Unfortunately there is no profiling information included in the return HTML in contrast to pages where the rendering completes.
It would be great if information similar to the one included in the HTML of pages that complete rendering could be added:

Even some limited information would be helpful.
