Don’t fsync Messages

When the opt.queue_no_fsync boolean setting is turned on, GreenArrow does not fsync() when writing messages to the disk-queue. This improves performance but increases the risk that if there is a crash it will cause message(s) to get lost or corrupted.

To control this behavior, see the disk_queue_writer_fsync configuration directive.

This is disabled by default.
