So technically the whole purpose of this is to provide faster startup
time after crash and not the consistency of data, correct?

I can't tell you right now, since I have never paid too much attention
to this (it just wasn't too critical to me). The reason I've sent my
original message was that I've just lost all my KDE settings and Mozilla
settings (all bookmarks, all e-mail accounts and all cookies). In case
of Mozilla and its e-mail accounts - subdirectories and files were
there, but Mozilla didn't have the mailbox configuration, so I've had to
create it again and then copy the mailbox data files over the newly
created ones.

As far as I can tell, they were being used at the moment of crash.

Power outage, or me being impatient when I need to restart my system
(never caused any problems while I was using EXT3).

Unfortunately I didn't get a chance to look at what was in its config
files after the crash... :(

Well. I didn't try to get this problem specifically, but I've had at
least two occasions when I've had such situation. I'll try this weekend
and see if this is something I can reproduce intentionally :)
