if i interprete my observations correctly, this is not a big deal, since
not every message sent to [tcpserver] will be transmitted in its own tcp
frame. at least on my box (ubuntu 8.04), they are sent seperately, if
there is at least a time interval of ~10ms between them. messages sent
with shorter intervals are concatenated into one frame. 
said this, i have to add, that the above is only true, if the number of
elements of a lists on the receiving side represent the framesize. for
instance, when i plug out the ethernet cable and fill the buffer on the
sender side, then plug the cable back in, i get one big list with ~5000
elements on the receiving side (don't try to print that one, it will
hang pd)
