/* These functions can be used to create a queue of small (or large)
* buffers and parts of files to be sent out over a socket. It is meant
* for writing HTTP servers or the like. */
/* This API works with non-blocking I/O. Simply call iob_send until it
* returns 0 (or -1). The implementation uses sendfile for zero-copy
* TCP and it will employ writev (or the built-in sendfile writev on
* BSD) to make sure the output fragments are coalesced into as few TCP
* frames as possible. On Linux it will also use the TCP_CORK socket
* option. */
