Even better solution: register a signal handler in your Bash session
for SIGHUP; the cygwin1.dll sends a hangup signal when CTRL_CLOSE_EVENT
is received.  Something like this:

    $ myclosefn() {
        echo "My close func got called." > $HOME/myclosefn.txt
        # TODO: add more clean-up logic here
    }
    $ trap myclosefn SIGHUP

I've tested this, so I know it works.

P.S. BTW, I didn't know the answer to this beforehand, but instead
actually looked at the source.  That's one of the beauties of open
source projects: questions like these can be answered by direct
inspection.  "Read the Source, Luke!" ;-)
