    Hmmm, so we issue an async sys_read(), what a get_file(fd) will return for
    a per-CPU kthread executing such syscall? Unless we teach context_switch()
    to do a inherit-trick for "files" (even in that case, it won't work if
    we switch from another context). And, is it all for it?
    IMO it's got to be either a per-process thread pool or a fibril approach.
    Or we need some sort of enter_context()/leave_context() (adopt mm, files,
    ...) to have a per-CPU kthread to be able to execute the syscall from the
    async() caller context. Hmmm?
