Also, quite frankly, I tend to find Uli over-designs things. The whole disease of "make things general" is a CS disease that some people take to extreme. The good thing about generic code is not that it solves some generic problem. The good thing about generics is that they mean that you can _avoid_ solving other problems AND HAVE LESS CODE. But some people seem to think that "generic" means that you have to have tons of code to handle all the possible cases, and that *completely* misses the point. We want less code. The whole (and really, the _only_) point of the fibrils, at least as far as I'm concerned, is to *not* have special code for aio_read/write/whatever.
