Sorry, I only can tell you why this failed (ran into similar things
myself): Invoking system makes up a new CLI for this very command and
there the stack size is in fact increased. But then this one is closed
and the effect is gone before the next statement (that opens a CLI for
itself again).

The solution I use for similar situations is to start applications
only through script files (plus icon and IconX for convenience) that
contain only two lines:
    newcli con:... from file.s
    endcli
(or newshell), where file.s contains the stack command and the call
for your application. This way you have _two_ additional windows on
the screen at least for short time, but that's not so bad (you can
give them identical dimensions and positions, so you hardly notice).
