The versioning does not work that way. whenever you save() the state
of an item it is persisted to the underlying datastructure independent
if the node is versionable or not. so if your server crashes after you
saved the item, it won't be lost.

you only need versioning if you want to be able to archive and restore
former versions of content.
usually node are not versioned every time there is a modification, but
at the end of more highlevel step, i.e. after you're done making all
modifications to several nodes and properties of a CMS page, before
publishing, etc.
