Prevent Ctrl-C kill native process

[Ilya Basin]

How to tell Cygwin not to kill a native process when I press Ctrl-C ?
I tried to run it in background, but it doesn't help, when its output
is piped.

Compare these:
( while true; do echo aaa; sleep 1; done & ) | ( trap '' INT; cat )
( while true; do echo aaa; sleep 1; done ) | ( trap '' INT; cat )

( /cygdrive/c/Windows/system32/ping -t localhost ) | ( trap '' INT; cat )
( /cygdrive/c/Windows/system32/ping -t localhost & ) | ( trap '' INT; cat )

The last command should not die, when I press Ctrl-C, but it dies
anyway.
