This is nonsense. It is perfectly possible to extend the stack accurately
in memory. That is easily true on the 387, but was also true on the 8087
with just a little bit of fiddling (I know that some people thought this
was not possible, but they just did not look hard enough, the Alsys Ada
compiler for instance used a stack model for fpt, and dynamically extended
this stack in memory, so this is certainly possible).
