I've found 3 places to patch in tramp.el, fixed in the emacs-23
branch. Under GNU/Linux I could not observe any regression. However, I
cannot test under Windows - could somebody, please, check it with a new
build? It shall be sufficient to open a large (>10kB) remote file,
using the plink method.

Best regards, Michael.
