yes, these problems bugs have been with us for a while.
But no, they won't be fixed in the imminent release of ESS 13.09-1

Actually, I've also seen occasional "break down" of help...
but then I'm running R sessions in an open emacs sometimes for
days, and in the mean time recompile the version of R running
inside emacs,.... so I'm used to occasional breakage of my
particular setup, and as I work with the principle "the source
is real" {and hence all expensive computations are save()d and
subsequently load()ed},
killing R (C-c C-q; no question asked with my default
'--no-save') and restarting it (M-x R) happen within a few
seconds as part of the reflexes my fingers learnt long ago...
