It happens. I once had a 'prompt' that wasn't supplying a valid default in non-interactive environments, and that was causing a stall. It's fixed now, and I learned something in the process:
When a smoker sees your script causing their rig to hang, they add your module to a blacklist so that it doesn't get tested in the future. They're happy to remove it once you've got the problem fixed, but you will need to alert them to do so. Visit http://lists.perl.org and subscribe to firstname.lastname@example.org. Then send a message requesting that smokers begin testing your module again, starting with version XYZ. Explain that good behavior has been re-established, and request removal from their blacklists.
The mailing list is low traffic, but it might not be inappropriate to follow up a week later mentioning the newfound success, and reminding any who haven't removed your module from their ban list to go ahead and do so.
