Thanks for answear Tom.

I doubt that this is a good thing to try to do during a panic exit.
In the first place, we don't know to what extent the process's
internal data structures may be corrupted, possibly causing
fcloseall itself to malfunction. 

Well, I put after fflush(NULL), so if data structures are corrupted, fflush will fail in any way.

In the second place, we might
wish to have a look at those temp files for debugging purposes.

On dev/debug are great, but on production, where disk spaces cost money, I think that a good idea.

Maybe guarded by ifdefs?
