The WP cache is not appropriated for very short term storage. Moreover a wrong value could have been stored between different requests. Replace the cache call with a transient expiring after 30s. Delete the transient right after reading it. Rename it to `qtranslate_slugs_matched_page`.

Not related to this patch, but I'm not sure about this update_post_caches and all similar updates in QTS.

Not sure if it's really needed, also because we are not modifying the post objects here. But I don't think it has anything to do with the caching query :) comment btw.
This is calling eventually wp_cache_add_multiple, so I think is not updating anything most of the time (it will only update if those keys do not exist already).
We may just add a comment to double check later or remove the calls now...
