"
This is because during wiredtiger_open for an existing database, we must pick up a checkpoint. (In the test, we have a trick to get the latest checkpoint, for MongoDB usage, the server gives us checkpoint info in the configuration string). The problem is that picking up a checkpoint fills/alters the shared metadata file, and that's not a readonly operation. I suspect to get this to work, we'll need to do something like temporarily turn off the readonly flag when updating the metadata file.
