If I remember correctly, I think 2K/XP has a timeout period for that
message.  If you do not return control back to the OS in a timely fashion,
the OS moves on anyway and assumes your application stopped responding.  Try
utilizing the WM_QUERYENDSESSION message as well, do some of your cleanup
work there as well, so that WM_ENDSESSION has less work to do and can return
back to the OS faster.
