Anyone can actually do this by editing or purging (not sure about the last one) a template, that'll schedule all transcluding pages to be purged. They aren't purged immediately because there could very well be millions of transcluding pages (this is true for [[Template:!]], for example) and purging them all would take way too long for a simple request. I don't see how we can resolve this bug except by adding some sort of job queue management interface for sysops, which would allow them to remove and prioritize jobs.

The job queue was designed to keep large operations such as this from being done all at once. As soon as you try to override that, you defeat the purpose of the cache to begin with.

I think having an interface to prioritize jobs kinda ruins the simplicity and transparency of the job queue. Suggest WONTFIX.

WONTFIX per demon.
