iperf server will not exit

[dann frazier]

[Impact]
After the iperf server has handled traffic, it fails to exit when ^c'd and must be forcibly killed.

[Test Case]
$ iperf -s
Another terminal:
$ iperf -c localhost -P 24
Back to other terminal:
^c^c^c

[Fix]
https://sourceforge.net/p/iperf2/code/ci/7c0ac64ebea38d0d9ff4d160db4d33bc087a3490/

[Regression Risk]
Someone may rely on the behavior that killing one thread kills the entire application. If so, this will change that behavior.
