- * It seems that Darwin 9.4 (Mac OS X 1.5) sendfile() has the same
- * old bug as early FreeBSD sendfile() syscall:
- * http://bugs.freebsd.org/33771
- *
- * Besides sendfile() has another bug: if one calls sendfile()
- * with both a header and a trailer, then sendfile() ignores a file part
- * at all and sends only the header and the trailer together.
- * For this reason we send a trailer only if there is no a header.
- *
- * Although sendfile() allows to pass a header or a trailer,
- * it may send the header or the trailer and a part of the file
- * in different packets. And FreeBSD workaround (TCP_NOPUSH option)
- * does not help.
