I recall I started with that position (free all), and I thought you
turned me around after this many years :-).

Do we have anything about this in style guide? I only found brief mention 
in "don't call cleanup from setup" section, which isn't even possible with newlib.

You don't need to clean up the following:                                                                                                                                                                          
                                                                                                                                                                                                                   
 * +malloc(3)+'ed memory.                                                                                                                                                                                          
 * Read-only file descriptors in persistent paths (i.e. not                                                                                                                                                        
   temporary directories).
