[Twisted-Python] twistd --uid and --logfile

[Zoran Bosnjak]

I am running twisted application from /etc/init/myapp.conf by exec
statement like this:
exec /usr/bin/twistd --uid=<id> --gid=<gid> --logfile=/var/log/dir/file

The problem is when log file is first created under /var/log/dir (dir is
owned by user id), the owner of the file is 'root', not requested user.
As a consequence, the twistd is not able to rotate log files.

If the logfile is already created (and chowned) before running twistd,
there is no problem. It looks like set uid/gid is called too late inside
twistd. It is suppose to be called before creating a logfile.

Is this a bug or am I missing something?
