Background app running as root and logout process

Hello everybody,

I have a tool application which runs as a daemon on
startup. It just links against CoreServices framework
and installs a notifier for the login event. When it
detects a login, it launches another application. This
second one will run as a background-only app (BOA) and
it links against Carbon framework. Both run as root.

The BOA calls RunApplicationEventLoop to install a
standard event handler.

My problem is that running in Mac OS 10.3.2, after a
user logout, the loginwindow process tries to quit my
BOA and it can't. The Console shows me this alert:

"login window: sendQuitEventToApp (myApp):
AESendWithMach returned error -1712"

The -1712 error means time out. After that, my BOA is
killed.

This is understandable because the BOA is running as
root and loginwindow as the logged user.

I have seen a different behavior on early Jaguar
versions like 10.2.3, where the BOA replied to the
quit apple event.

I don't want my BOA get killed because I need to do
some post-processing after RunApplicationEventLoop
call. Some ideas?

Thanks in advance ...
