You _think_. I do, too. But I'd like to _know_ before I tell people their
compiler is broken!

Of course it will get bigger. It's not my intention to do that. I was
referring to ZEROing arrays that are NOT initialized, and I'd use memset for
that. If we make it mandatory for compilers to zero the bss section, we can
leave that away. But right now, we don't seem to know that for sure!
