okok, i shouldn't write emails, when i'm half asleep. i just double
checked (with a small program) and you are completly right. i think i
have just confused something i even don't remember quite now. 8-)

read() may return before it has received a maximum number of bytes, and
on linux it seems as there are more then one reason for this. a full TCP
packet has benn received, the other side closed the connection or the
read was interrupted by a signal.

i hope i didn't confuse anybody.

best regards ...
