Previous/Next page links maintain all GET variables

The newer/older entries pagination system takes any query string in a inbound request, and includes it in the links generated for the newer/older entries.
This causes problems when you put wordpress behind a cache, because all it takes is some bot trying a joomla hack to mean all visitors suddenly have a version of that page, including the bad query string, very visible.
Note, in the 'Newer/Older' links at the bottom of the page, that "test=true" will be retained.
These should only really keep query-strings that wordpress knows it'll need, if you're including them? Else, you can basically poison someone's cache with this.
An example of the really bad query string poisoning a cache:
