Description

The MemoryManager is tied to a WriterOptions on create, which can occur in a different thread from the writer calls.

This is unexpected, but safe and needs a warning not a fatal.

    Preconditions.checkArgument(ownerLock.isHeldByCurrentThread(),
        "Owner thread expected %s, got %s",
        ownerLock.getOwner(),
        Thread.currentThread());
