Oracle crashes on Windows shutdown

Just curious if any of you have ever had a problem with Oracle coming back up after a \
"crash" forced by a normal Windows shutdown (i.e. no disk or other hardware problems - \
just a reboot)?  

I know there are various registry settings to determine if Oracle shuts down, how it shuts \ down (normal/immediate/abort), and how long Windows should wait. And I know that Oracle \ Support's canned response on the subject is:  

"If the entry's are not set, stopping an service will do WORSE then an shutdown abort. \
Windows NT / 2000 will just "clean" the memory. This could be compared by a kill -9 on \ unix. This is likely to make any cold backup useless. "  

And the Oracle Admin doc says:  

"If ORA_SHUTDOWN or ORA_SID_SHUTDOWN is set to false, then shutting down OracleServiceSID \
will still shut down Oracle9i database. But it will be an abnormal shutdown, and Oracle \ Corporation does not recommend it."  

But, has anyone ever actually seen it cause a problem in real life? I've seen Windows \ shutdowns force thousands of Oracle crashes over the years and not once have I seen it \ cause any trouble for Oracle on startup - other than a little crash recovery of course.  

Thanks,
Brandon
