Don't enable this unless you have a really good reason to clean + things up manually. + +Buffers allocation policy +CONFIG_FEATURE_BUFFERS_USE_MALLOC + 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.
