Ignoring the internal language details, I extend this slightly to:
Server is running.
Create or change an existant object.
Yank the power cord out of the wall (ie crash/ungraceful shutdown)
Restart server.
New object still exists, or changed object is still changed.
This is actually not literally true as I only guarantee recovery back
to the last full cache flush which is typically within single-digit
minutes.
