I'm with Love on this one.  XPG and the SUS have specified for better
than a decade that the iov count for writev(), readv(), and the struct
msghdr used with sendmsg() and recvmsg() is to be of type 'int'.  To
create a new interface that was so obviously modeled on those but
differ on that point, I would expect some sort of justification for
the difference.
