Not commenting on the general issue, but the EA caching thing is a
non-starter. Reading an EA is just like reading a normal file, its not
stored in the dirent. So, given that its as fast to read a block as it
is to read the few bytes of the mimetype string, reading EAs is bound to
be the same speed as sniffing.
