Yes, that makes sense. I expect this could be done by extending the
existing requests with a flag saying the result is already cached.
And then the filesystem can either reply with a special "cached data
is valid" code, or it can reply normally with the fresh data.
Oh well, you can turn off caching if it bothers you :) OTOH it would
be rather hard (and probably against the point) to try to extend the
sftp protocol to handle cache coherency. Sshfs is not meant to be a
normal filesystem (although some people are trying to use it for home
directories and such), just a simple way to access remote files.
