Remove O_SYNC from low-level file-writing flags.
The man page for open(2) says the following to the O_SYNC flag: 'O_SYNC
provides synchronized I/O file integrity completion, meaning write operations
will flush data and all associated metadata to the underlying hardware.' This
flag results in a high delay when files are stored in casx, e.g., several
seconds for medium-sized files such as 23 MB. Since just does not care about
persistency, this strong synchronization mechanism is not required and is
deactivated.
