oh, I didn't mean your email, I don't mind people like you asking
about stuff like this, what I was referring to was all the emails
telling me "samba has a security hole because it uses mktemp()".

ok. the main thing to find out is if it is a problem on other
platforms too, in which case we might switch to using setegid() by
default again.
