Hello all,

I've just tumbled on an annoying problem concerning the deallocation of
Files.File. Apparently, when creating or opening large sets of files, GC
doesn't work as expected. For example, the following code will quickly blow
up your memory, although the same variable, f, is always use to store the
successive Files.File:

MODULE PrivMemOv;

 IMPORT

  Dialog, Files, Kernel, Strings;

 PROCEDURE Do*;

  VAR

   f: Files.File;
   s: ARRAY 12 OF CHAR;

  BEGIN (*Do*)
   LOOP
    f := Files.dir.Temp();
    Strings.IntToString(Kernel.Allocated(), s);
    Dialog.ShowStatus(s);
   END;
  END Do;

 END PrivMemOv.

Moreover, inserting Services.Colllect in the loop just slows down the code
dramatically, but doesn't cure the problem.
Hence my questions: Is it a bug? If not, it's a very annoying feature, since
it forbids any extensive management of files. How to do in these cases?
