It occured to me that I'm using the term "cache coherency" incorrectly here. What I really mean to say is that Windows is in charge of all file operations and so can and does maintain a consistent cache of file data and attributes because the only path to the file is through the OS. Cygwin can't because a cygwin process can't (easily) know what other processes are doing to a file. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
