Quick! Get into the file system and relink an accidentally deleted file, while it's still held open(?) by "some" application. Best of luck with that approach. It may work from time to time but, I can guarantee you that it will let you down when you need it most.
Linux file systems SUCK! Netware has had a filesystem that allowed restoration of multiple versions of deleted files(Salvage) since 1992, at least! More recently, they came up with Novell Storage Services(NSS) that not only has "Salvage" capabilities, it also has Copy On Write which basically allows you to backup open files and more. Microsoft, not to be out done for more than a few years, released their Volume Shadow Copy which tries to be similar to NSS. Meanwhile, back in Linuxland we still piss around with antiquated relics like Ext2/3 and oddball hacks like this article offers. Make sense man!
Why doesn't Linux have a recoverable file system with block level support for things like backing up open files? Don't you think that Ext2/3 are getting rather stale when compared to the file systems of commercial operating systems?
