on 6.4.1 threaded RTS was used only in specially build libs. in
debugging versions of libs and GHCi single-threaded RTS was used.
developers of threaded programs was complaining about this situation
because it makes their debugging much harder. so, in 6.4.2 ghci (and
ghc) and debugging libraries was changed to use threaded RTS

obvious workaround is to continue to build GHC and debugging libs with
non-threaded RTS on the platforms where multi-threaded RTS is not
reliable yet
