Perhaps--but that adds to your "just as valid" the clarification "but implemented very differently." If I open a 444 file with GraphicConverter from my Desktop, change it and try to save, I get told that I can't do it because of permissions. Now let's look at one with PhoneDisk. Pick an app I'm willing to risk, … IMDB. Get info on the icon: default app is TextEdit! but it says I can read and write. See if ls -la agrees and what kind of file.

Often in Mac OS X modifying a file actually results in creating a brand- new file and replacing the existing file with it. It's not hard to imagine that in such a case, if the creation of the new file failed silently due to ownership and permissions issues, the next operation to move that file into place to replace the old file would fail with a LOF during read error. -- Send responses to the relevant news group rather than email to me.
