	Simple.  Calls to system() (or Execute()) cause a program to be
run on another process.  So they set the stacksize for that other process,
not yours.

	Changing your own stack is a bit more complicated.  It's pretty easy
in assembler, but in C you have to be more careful, especially with
exit() and stack-checking.
