+ help
+ There are 3 ways BusyBox can handle buffer allocations:
+ - Use malloc. This costs code size for the call to xmalloc.
+ - Put them on stack. For some very small machines with limited stack
+ space, this can be deadly. For most folks, this works just fine.
+ - Put them in BSS. This works beautifully for computers with a real
+ MMU (and OS support), but wastes runtime RAM for uCLinux. This
+ behavior was the only one available for BusyBox versions 0.48 and
+ earlier.
