Well, sure, GnuCash cannot control the OS's file system semantics. And
indeed, in pretty much every modern OS there is a delay from when an
application "writes" something to the file system vs when the OS flushes
that file system out to the storage media (HDD or an SSD). There are some
was that applications can inform the OS that it it wants it written *now*
(e.g. flush the IO). However, in a power outage, all bets are off.
Save Early, Save Often!
