That's how the regular logon does it, don't see why it has to leak.
Running in session 0 means it's possible for non-elevated users, i.e.,
users that aren't admins, just regular users, to launch shatter
attacks on services.

Gee thanks, yeah, I got that, I still think it's a security issue,
that is, a bug.  See the original post, any program can read/write to
any executable in cygwin without escalation because I'm the owner.
