Coda has some special case handling for so-called 'virgin files' i.e. open files that haven't been closed (only create, but no store operation has been done). Also I'm not sure how we handle unlinking files that still have an open file reference in all cases. My guess is that only some 'delete_me' flag is set, but the directory entry might still exist on the server or something. > A 486 client seems to be a good testbed for race condition testing. > Or should I rather shut up and upgrade my hardware? > I am afraid the race will show up anyway, once in a million... when you > are running your life's most important application... :) Slow machine, it could very well be a slight difference in semantics between connected and write-disconnected operation.
