Currently, this is a convenience method roughly equivalent to:
for chunk in iovec: fd.write(chunk)
It may have a more efficient implementation at a later time or in a different reactor.
As with the
write() method, if a buffer size limit is
reached and a streaming producer is registered, it will be paused until the
buffered data is written to the underlying file descriptor.
Call this to cause this FileDescriptor to lose its connection. It will first write any data that it has buffered.
If there is data buffered yet to be written, this method will cause the transport to lose its connection as soon as it's done flushing its write buffer. If you have a producer registered, the connection won't be closed until the producer is finished. Therefore, make sure you unregister your producer when it's finished, or the connection will never close.
