Just from my comment in bugzilla:

To be honest, I'm not really happy with that patch. Using a
setfileinfo call for a read-only open is just a broken
protocol, and having to put some complicated code paths for
security-relevant stuff in makes me feel very, very uneasy.

There is no other way like a qfileinfo for the r/o variant
of posix open?
