>From Sandeen's blog, March 2009:

"I dunno how to resolve this right now.  I talked to some nice KDE folks
on irc; they basically want atomic writes, either you get your old file
or your new file post-crash; and tempfile/sync/rename does this – but
the fsync hurts on 78% of the Linux filesystems out there.  So their
KSaveFile class doesn’t fsync.  So what to do, what to do.."



That's 4 years ago.  Is it possible the KDE devs are still not using
fsync?  Sure seems likely given Markus' problem.
