I tried to reduce \skip\footins, not to increase it

No, no. I know that such an action should remain exceptional, and this  
is what I need: an exceptional way to decrease \footins on a single  
page.

Is \dimen\footins different than \skip\footins???

Several people suggested I use \enlargethispage. I think you don't  
understand the problem: I want to insert an extra line of text,  
_without moving neither the text upwards, nor the footnotes downwards_.

\pagebreak works if you want lesser lines, I need an extra line.  
\nopagebreak has never worked. If I use a box to force the extra line  
of text, the footnote is broken.

I really need a means to fiddle with \footins on a single page. And I  
have the impression that (La)TeX does not allow fine-enough control on  
footnotes...

Thanks
