Two questions:

* This seems to say that something like this won't work:

  char *the_ptr;
  the_ptr=malloc(the_size);
  _go32_lock_data_memory(the_ptr,size); (syntax? not sure)

  because later the data may find itself moved somewhere (despite being
  locked?) while the locked memory stays put?

* What is sbrk()? It sounds like the "malloc behind malloc"... as in, the
  routine to allocate more heap from the kernel or DPMI host, rather than to
  allocate more for the app from the heap.
