Review comment:
What ORC does is writing the content. Then it attempts to close the
`liborc::OutputStream.`
https://github.com/apache/orc/blob/7e12a8ccac81548fde6e5d0538da2e68c77df601/c%2B%2B/src/Writer.cc#L369
The issue here is of course that we shouldn’t actually close the
`arrow::io::OutputStream` because at least in some instances (such as when we
are using `io.BytesIO`) we don’t exactly want it closed right after the
flushing.
