This PR fixes the immediate problem. But I think at some point we should add these documents to an index and then use background task to update the site map in bulk.

Locking during publish will slow down publishing for a busy site.

Yeah, I thought about doing background processing like it happens with indexing. Why I didn't go down that route, apart from it being much more complex, is that compared to indexing, such sitemap updates should be much quicker and don't inherently require such batch processing.

We'll yeah but if you are publishing/unpublishing very frequently, now every request will cause a lock. Again you do not need to implement it here. But I think we should submit an issue so it is tracked and one day this will be converted. At least we know there is an issue that should be addressed at some point.
