For fsck sake, folks, if you have bloody /proc, you don't need that shite at all! Just do execve on /proc/self/fd/n, and be done with that. The sole excuse for merging that thing in the first place had been "would anybody think of children^Wsclerotic^Whardened environments where they have no /proc at all".
