We have been doing this without any problems.  Not to say that I know that
there aren't any
problems with it, but we haven't had any problems that we attributed reading
in one thread
while writing to another.
As far as sending an ACK for one packet while another thread tries to send
another packet,
that would need to be handled anyway because with TCP even if you aren't
reading from the
socket a new packet coming in needs to be accepted and ACKed anyway and then
the data
should be there when you do read from the socket.
