When saving remote files thru tramp ssh (2.1.7, running on Cygwin Emacs 21.3.50.1), my PC CPU surges to near 100% with both in/out network traffic peaking also. By setting verbose level to 8, it seems to be stuck at "Tramp: process-buffer nil", then "Tramp: check-remote-echo nil". At level 10, it stays pretty static at "Tramp: process-buffer nil", then blinks a few times for "Tramp: *tramp/ssh
address@hidden run".
