Yes.  The free'd memory is not returned to the system, it is left
allocated to the running program.  So neither physical nor virtual
memory sees the deallocation, because these reports come from the DPMI
server that is external to the program you run.

You can't.  You will need to hack the sources of `malloc' and `free',
or use a replacement `malloc' library.
