On Unix you'd just arrange for your job to ignore sigINT itself, overriding
the withSignalHandled setting. The various online documentation systems are
all on Linux and don't document win32-specific modules as a result, but it
looks like you might be able to use

    withCtrlCHandler id realActionGoesHere

on Windows. (Someone with Windows knowledge needs to verify that; it's
nested under another withCtrlCHandler in withSignalHandled, and I have no
clue how they would interact.)
