There are a small number of *trivial* VFS changes that would help immensely. I'm not going to code around bogosities that should not be there in the first place; If I wanted such bogosities, I'd work on Linux, where the prevalidation of memory access makes it a bit faster on combined copyin/out operations, but opens a nice race window each time you invoke kernel preemption (can you say "clone()"?
