I am not certain why/where xarray is caching the open file, though - I would have thought that a new file instance is made for each `open_dataset()`. I am not certain whether seeking/reading from the same file in multiple places might have unforeseen consequences, such as when doing open_dataset in multiple threads.

I am mildly against subclassing from RawIOBase, since some file-likes might choose to implement text mode right in the class (as opposed to a text wrapper layered on top). Pretty surprised that it doesn't have read()/write(), though, since all the derived classes do.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1310058435
