On second thought, this description is a bit misleading.  Actually
the problem might occur in pure local circumstances as well.

What happens is that a parent process sets the console to raw mode and
then starts a child process.  When the child process starts, Cygwin
might set the console back to cooked mode without the child process
actually requesting that.  When you now press Ctrl-C, instead of just
returning the ASCII value of that control code, a SIGINT signal is sent
to the parent process.
