That is unexpected. writev() may fail if the sum of iov_len would not fit within ssize_t with EINVAL, but unless your "the OSS I/O size limit" is the same as SSIZE_MAX, what you have above is not quite the same. Does your build work with NO_WRITEV=Nope? I think I saw it asked a few times but I do not recall seeing it answered. At least we know xwrite() seems to work well enough on your system, which is what the writev() emulation is written in terms of, so I suspect it would.
