I don't think it wrecks legibility, since it's a C idiom. People reasonably experienced in C will read "for (;;)" as an infinite loop just as well as "while(1)"

I don't think it wrecks legibility, since it's a C idiom. People reasonably experienced in C will read "for (;;)" as an infinite loop just as well as "while(1)". That said, it might be a little confusing for beginners (or others who don't use C very regularly).
