The second part is always OK.
What benefit does this have? It's on the stack and not long-lived...
Stacks are surprisingly small those days to reduce virtual memory
Watch the apple branch playing rlimit games in toplevel.c due to this.
The less is used
Actually the reason Apple's branch does that is because the default on
pre jag was
only 512K which causes some semi big programs to fail when going though
Now Jag and beyond is 8M which is nice.
