I did find a workaround for our current problem (some of our queries had 
to be uncached anyway, and since cached and uncached is somehow dealt 
with in a parallel universum, this case could solved by playing around 
with that).

But I find this issue so peculiar that I would like to see a real solution.

I think you refer to this note [1], and I read that as 'just an idea'. I 
could not find any traces of it in the core.

And from [2] it seems the problem still exists in 4.7.x

I checked the code in class tslib_content_Content and nothing seems to 
have changed yet.

My idea is almost the same as Bernard Krafts suggestion to decrement the 
value [3] (notice this post is from 2005!):

    When I add:
        if ($originalRec) {
           $GLOBALS['TSFE']->recordRegister[$originalRec]--;
        }
    at the bottom of the "CONTENT" method it works as expected ...

Are there any reasons not to include this in the core?
