* close operation will finish as much as possible. A stream that failed
* to close will still return IO_ERROR_CLOSED for all operations.

* otherwise there might be a loss of data as all data might not be written.

* triggering the cancellable object from another thread. If the operation

* Cancelling a close will still leave the stream closed, but some streams
* can use a faster close that doesn't block to e.g. check errors.
