Wheeler: Fixing Unix/Linux/POSIX Filenames

We have that -- that's what file descriptors are. It would be nice if programs passed them back and forth more often, but my guess is that they mostly get used where they should, and to make their use more ubiquitous you'd need to radically re-architect a lot of stuff. (If one wanted to be provocative, one could claim that the whole goal of EROS/Coyotos is to figure out what that re-architecting looks like.)
