    ihandle: Make sure we don't ih_attachfd invalid FD
    
    Right now, if you give ih_attachfd_r an invalid fd, and fdLruHead is
    NULL, we'll return an FdHandle_t* for an invalid fd. Nowhere in the
    code is this possible right now, but the implementation of
    ih_attachfd_r and ih_attachfd doesn't make this very clear.
    
    Ideally the "close some fds and retry" behavior in ih_attachfd_r will
    be split out, so this code could be easier to follow, and we could
    implement open() EMFILE retrying for icreate operations. But for now,
    just make the current behavior clearer, so future modifications do not
    introduce such mistakes.
