This is the correct behavior.  Under DJGPP/DPMI, the use of memory is
highly optimized for speed and efficiency.  When you free a block of
memory, it is added to a pool of free memory blocks so that your program
can reuse them with very little overhead.  See chapter 15.2 of the FAQ
(v2/faq202b.zip from SimTel) for more information.
