Possible optimization Benny, I haven't thought this through to it's
extreme yet, but.... could you possibly skip magic lookup on files
with the exec bit set? Noting the way that Windows works, it's highly
rare to have a file with non extension (you have to fight to get an
app to not auto add an extension), and except in the case of limited
filesystems should the x bit be a pretty clear indicator that the file
is an application?
