<p><b>Notes:</b>
Increasing the size of a block past a 64K boundary will fail if the
next descriptor in the LDT is already in use.
Shrinking a block past a 64K boundary will cause some selectors to be
freed; DPMI 1.0+ automatically zeros any segment registers containing
a selector freed by this function.
