In GNU Emacs 18.50.3 of Wed Aug 17 1988 on rigel (usg-unix-v): C-g does not interrupt disk I/O operations (file reads, saves, autosaves, etc.). This can be a problem when the files involved are large and you're writing over a slow network. It is barely tolerable over an unloaded Ethernet... what will happen when I start mounting file systems on the other side of the Atlantic over a 56kbaud line? (If I recall correctly, Emacs likes to read/write the whole buffer in one system call. If system calls aren't interruptable, perhaps this is a bad idea.)
