just an idea I just had: I think reusing the UDP keep alive mechanism 
also on TCP is not a good idea (.e.g. if the TCP connection is lost 
...). Maybe it could be possible to mark TCP connections as "keep 
alive". Then there would be a dedicated TCP/TLS keepalive process which 
loops over all currently opened TCP connections and if it founds a TCP 
connection with the "keep-alive" flag it sends CRLF.

just an idea....
