This doesn't quite qualify as a bug, but it's something I think should be changed. Currently writev(3) allows a maximum of 8 iov's in the io vector; if more than 8 are specified, it returns EINVAL. IMHO, this is far too small, especially for an arbitrary limit: SunOS supports up to 16, and OSF/1 (aka Digital UNIX) supports up to 1024. I'd like to see MAX_IOVEC increased to at least 16, and preferably more than that.
Also, note that MAX_IOVEC is not the correct name for this parameter: a brief survey (consisting of DEC OSF/1 and NetBSD-current) seems to indicate that UIO_MAXIOV is the right name.
