Since you do not know if the user will save it again (or when) I would
avoid doing too many checkout (some cmis systems blocks the document when
you do a checkout).

I would suggest the following pattern:

open, retrieve read-only, mark the version number

save,
1) control version numbers (did anybody else change the document in cmis)
   warn user if different.
2) checkout and checkin the changed document
