/**
* This test is only for the WiredTiger storageEngine
* Test nojournal option with wiredTiger replset. This test will fail with mmap because
* unclean shutdowns are not safe. If running without a journal, WT starts up from last
* valid checkpoint, so should recover.
*
* Start a set.
* Insert data into collection foo
* fsync secondary member 1
* Kill -9 secondary member 1
* Add some more data in a new collection.
* Restart member 1.
* Check that it syncs from the last checkpoint and data is there.
