you are right is not a mintty only issue.
Same happens in xterm


$ which ping
/usr/bin/ping

$ ping 2.2.2.2
PING 2.2.2.2 (2.2.2.2): 56 data bytes

It sticks here forever, CTRL+C ineffective.
Process Explorer or Task Manager are needed to kill the process.
Also kill -9 PID is ineffective

On the old cygwin.bat (aka windows cmd)
CTRL+C is effective

  64 $ ping 2.2.2.2
PING 2.2.2.2 (2.2.2.2): 56 data bytes

----2.2.2.2 PING Statistics----
2 packets transmitted, 0 packets received, 100.0% packet loss
