@lanodan jwz is, in general, a bit of a cock.
I don't know why people put so much uncritical faith in his stuff.
When it comes to a lot of his writing, he presents himself as unambiguously correct in all cases and always other people's problems.
I worry people with this kind of attitude distort the truth, and sure enough in his long series of "I told you so" posts about other screensavers bugs, he neglects to even mention xscreensavers own, despite promoting it as bulletproof one-true solution
