Ok I've done some test with a fox application we've built (a smaller one):

Memory with no SYS(1104), RELEASE ALL and FLUSH

Memory Usage (Ko) Peak memory usage (Ko)
13316 13356 (Top level form)
15808 15808 (Open a child form)
14812 15820 (Close the child form)

Memory with SYS(1104), RELEASE ALL and FLUSH in the Unload of the child form

13312 13352 (Top level form)
15216 15220 (Open child form)
14444 15224 (Close the child form)

Same test with minimize

13388 13420 (Top level form)
15864 15864 (Open child form)
14832 15872 (Close the child form)
3552 15872 (Minimize the app and maximize)

The SYS(1104), RELEASE and FLUSH doesn't seem to change a thing... and I tried to change the SYS(3050,1) value and I got the same result.
