Let's wait a few more days and see if you really see no more hangs. If you report back that the hangs are gone, I will have some explaining to do on what is going on behind the scenes, so we can dig deeper and discuss how to fix it. In the meantime, Andrés sent me a mail off the list, telling me that he is actually seeing an increase in hangs with this patch which is rather surprising, to be honest. @Andrés: Is that correct? If yes, what Emacs version are you using? What are you doing when the hangs occur and can those be canceled (ctrl+g)? Thanks to both of you for taking the time and your patience.
