 Well, even the Linux kernel does it itself at boot (i.e. clearing the BSS 
at entry), obviously being just another bare metal app, although some bare 
metal loaders included with monitor firmware that are used to start Linux 
are developed enough to do it before passing control, such as ones that 
talk ELF.
