A mis-use of L{IUNIXTransport.sendFileDescriptor} caused the connection to
be closed.
Each file descriptor sent using C{sendFileDescriptor} must be associated
with at least one byte sent using L{ITransport.write}. If at any point
fewer bytes have been written than file descriptors have been sent, the
connection is closed with this exception.
