The impression I got was that some internal subroutine of getaddrinfo
had a broken error-handling convention (ie, "return a numeric address
value or -1 on error").

Seems unlikely.  I suppose you could argue that we shouldn't be using
getaddrinfo on the netmask field at all; there's certainly not any value
in doing a DNS lookup on it, for instance.  Maybe we should go back to
using plain ol' inet_aton for it?  (Nah, won't handle IPv6...)
