Non-blocking pipe

Hello,
Would this be an acceptable way of creating a non-blocking pipe.
Basically I want to create kind of a server client arch.
This code would be in the server, and I don't want to have to wait for
clients to read before moving on to the next client. One problem I
can see is if a client leaves/dies and never reads from the pipe(but I
could have some trap/cleanup stuff in the clients for that).

# assigning fd 3 to the pipe
echo "exec 3>myfifo && echo 'a' >&3 && echo 'b' >&3 && echo 'c' >&3 &&
exec 3>&-" | at now



Chris.
