While I agree that perhaps changing the function signature is a little
too intrusive considering it's been that way for a long long time (I
would wager) , I do think that yes, there should be a sanity check but
more importantly the documentation should explicitly state the
limitation or restriction despite the parameter type is a 4 byte
integer. Otherwise people like myself will assume that all 4 bytes can
be used ;)
