  45 </I>&gt;<i> The attached patch fixes the problem that IRCServices don't flush the
  46 </I>&gt;<i> write buffer when the connection to the server is establised and data
  47 </I>&gt;<i> has already been written to the buffer.
  48 </I>&gt;<i>
  49 </I>&gt;<i> This caused the server to disconnect IRCServices after a timeout
  50 </I>&gt;<i> because of no data has been sent. Solution has been to send
  51 </I>&gt;<i> IRCServices a HUP signal right after starting it. I was able to
  52 </I>&gt;<i> reproduce this problem on all of my machines (Linux on HPPA, Linux on
  53 </I>&gt;<i> amd64, and Mac OS X on i386).
  54 </I>&gt;<i>
  55 </I>&gt;<i> I think these messages describe the same problem:
