Thanks for your comments :)

I have probably been doing some unnecessary work here.
As suggested, I created a test program in C with a simple function which had a
parameter of size > 4K.
The assembly then shows a call to _chkstk, which probably does the job needed.

See

http://msdn.microsoft.com/en-us/library/ms648426(VS.85).aspx 

or e.g.

http://www.codeguru.com/cpp/v-s/debug/article.php/c19241/Adventures-with-chkstk.htm

Maybe we should be using this function instead?

I also believe the guard page is put between committed and uncommitted memory,
see e.g. the comment in WebKit\Source\WTF\wtf\StackBounds.cpp in the Windows implementation.
