Tim is right.  gnet_conn_readline() reads one byte at a time.  In order to
get faster IO, you'd need to read into a buffer and then check if there's
a line.  gnet_conn_readline() does not buffer.

In GNet 1.1++, TcpSocket will derive from IOChannel, so you will be able
to use GLib 2's g_io_channel_read_line().  GLib 2 IOChannels can buffer.
