Of course, there is a checkpoint, and then there is a checkpoint. :-) Crash recovery is all about when did the checkpoint complete, not when did it begin, correct? :-)

Then the database will say these files require media recovery. Then you, the expert DBA that you are, will do an "alter database datafile {filename} end backup;" followed by an "alter database open;" and all will be well. :-)  

My general approach to bouncing a database that typically takes a long time to shutdown immediate is:

1. shutdown abort
2. startup restrict
3. shutdown immediate

BTW, unless I'm mistaken, checkpoints occur automatically at the least every 3 seconds.

What happens if you have datafiles in backup mode and you try and do a startup force?  

select

        'alter database datafile ' || '''' || HYPERLINK
"http://f.name"f.name || '''' || ' end backup;'
from v$datafile f, v$backup b
where b.status = 'ACTIVE'
and f.file# = b.file#
/

run the generated SQL.
