It seems that store_user_info() and read_user_info() do SysObj’s write/read, which use librados::ObjectWriteOperation and librados::ObjectReadOperation, which are supposed to be atomic. How could read_user_info() get either partial or inconsistent content, such as the old xatters with newer content?
