Ahh. I should have read that email more carefully. If xargs broke,
that _will_ break actual scripts, yes. Do you actually set the stack
limit to insane values? Anybody using toybox really shouldn't be doing
32MB stacks.

So I still do wonder if this actually breaks anything real, or just a
test-suite or something?
