I believe that I have confirmed the above statement below.  And more,
importantly that normal applications do not receive CTRL_SHUTDOWN_EVENT
events.

OK, I tried again this time using fetchmail which usually runs as a
service under my account -- which makes it perfect for this kind of A/B
testing.

When fetchmail is started from the SCM via cygrunsrv, its log indicates
the following during shutdown:

    fetchmail: sleeping at Mon Mar 24 09:16:43 2003
    fetchmail: terminated with signal 15
    /* Windows reboots */
    fetchmail: starting fetchmail 6.2.2 daemon
    fetchmail: sleeping at Mon Mar 24 09:21:36 2003

When fetchmail is started as a normal application, its log indicates the
following during shutdown:

    fetchmail: sleeping at Thu Jun 12 07:35:38 2003
    /* Windows reboots */
    fetchmail: removing stale lockfile
    fetchmail: starting fetchmail 6.2.2 daemon
    fetchmail: sleeping at Thu Jun 12 07:40:06 2003

The above indicates that a CTRL_SHUTDOWN_EVENT event is *not* received
by fetchmail when running as a normal application.  IMO, we can
generalize from this test that only services and their children receive
CTRL_SHUTDOWN_EVENT events during shutdown -- never normal applications.
So, my confidence in this change has been restored.
