   Technically, this shouldn't violate safety as an fsync will still flush out the data synchronously.
   
   We used to have some versions of these previously done at the couch_file or couch_db_updater level. There was an 8KB read-ahead and a delayed commit option. These ones are a bit simpler and easier as they are using OTP provided functionality.
   
   Locally on MacOS I haven't see a huge perf difference (with fabric_bench) but perhaps this might help in case with a remote block devices where write IO calls are throttled or somehow behave better if they are in larger blocks.
