I think I have a solution, although the problem is interesting. 
 
I changed the read code to be the following:
 
        if(socket.data_waiting) 
        {
            var numRead = socket.nread;
            buf = socket.read();
            if (numRead != buf.length)
            {
                log("2 - " + numRead + " vs. " + buf.length);
            }
            client.socket.write(buf);
            continue;
        }
        sleep(1);

And noticed that the string being returned from "read" had the wrong number of
bytes occasionally.  I assume there are embedded \0 characters in the telnet
responses?
 
Anyway, switching to the following read code seems to help:
 
        if(client.socket.data_waiting)
        {
            var numRead = client.socket.nread;
            if (numRead >= 512) numRead = 512;
            
            while(numRead > 4)
            {
                buf = client.socket.recvBin(4);
                socket.sendBin(buf, 4);
                numRead -= 4;
            }
            
            if (numRead > 0)
            {
                buf = client.socket.recvBin(numRead);
                socket.sendBin(buf, numRead);
            }
            continue;
        }

I'll see if that has any weird effects.
 
I'm signing off now.
