Every run that starts a real mongod ends with this on a shutdown thread,
against a build whose
tests all passed:
```
Exception in thread "Thread-77" de.flapdoodle.reverse.TearDownException:
tearDown errors
at
de.flapdoodle.reverse.TransitionWalker.tearDown(TransitionWalker.java:298)
at
org.grails.datastore.gorm.mongodb.embedded.FlapdoodleMongoBackend$RunningMongod.stop
Caused by: java.nio.file.NoSuchFileException:
/tmp/temp--.../workingDir.../mongod.pid
```
The server is stopped twice. `EmbeddedMongoLifecycle` stops it when the
application context closes,
and the JVM shutdown hook - which is there for a context that never closes -
stops it again when the
process exits. Flapdoodle removes the process directory as it tears the
server down, so the second
teardown fails on the files the first one deleted.
Stopping is idempotent now, and so is starting a server that is already
running. The in-memory
backend already tolerated both; a spec covers each.
