Listen mode doesn't flush stdout

What steps will reproduce the problem?
In one console:
  $ mnc -l -p 6082 224.10.10.10
In another console:
  $ echo -n "test" | nc -q 0 -u 224.10.10.10 6082

What is the expected output? What do you see instead?
Expected to get "test" (with no newline).

Instead, you get nothing until another packet is sent that contains a newline.

What version of the product are you using? On what operating system?
r4 on Slackware Linux 11.0 with kernel 2.6.18.1

Please provide any additional information below.

The following patch flushes the output buffer after writing each received
packet:
