missing a trailing newline, and i'd just call puts() to bypass useless format 
string parsing

no space before the "(", and i'd use puts() here

this doesnt sit well with me.  i dont see why this matters ... we dont have 
any delays today, and i dont think we should introduce any.

puts()

what use is there in having a return value ?  the do_reset() funcs today dont 
return, which means they have no meaningful reset value.
