__dpmi_get_free_mem_info will give you a lot of statistics, but many of
them are not really meaningful.  For instance, `free'd memory is not
released to the DPMI server, but is kept for future `malloc's.  So
`free'ing will not increase the amount of memory that this function will
claim is available.
