Sure, but I do not know if OtherApp is going to be a Cygwin app or not.
Sometimes it is not, so calling Cygwin's kill() might not be appropriate.
In any event, this bug effects typing Ctrl+C in a console window too.
When I run "gcc -pipe file.c" and CPP is running, I type Ctrl+C and
CPP does not die. I then type Ctrl+Alt+Del to see the running tasks
and GCC is gone but not CPP (CPP continues running then exits).
