Comment(by rransom):

 It's also not quite clear what we want to do for lengths in general -- do
 we sometimes use negative return values to indicate failure of a function
 that would normally return a length?  At the very least, we need safe
 (overflow-checking) unsigned-to-signed and signed-to-unsigned cast macros.
