Hi All:

  The following patch is cosmetic but I think is good.
  It just calls free in exit to de-allocate all the memory allocated by the
atexit() function. I know that's not necesary because we will release all
when leaving the control to the OS but it helps to track memory leaks. My
editor is registering 23 functions with atexit and they are reported all the
time by YAMD. Of course I can remove these entries from the report using
a script but I think that's the best.
