god stop not working

I am using Appscale 1.5 on a Debian 6.0.3 XEN system.

In my research I have added a process to the AppScale architecture.

This process gets started (and re-started if I manually kill it) using the
'god' infrastructure.

This process does not get stopped when appscale-terminate-instances is run.

I believe this is a problem with the underlying 'god stop' functionality.
To verify this I removed the 'force kill' logic at the end of appscale/AppController/terminate.rb
With the 'force kill' removed, many AppScale processes continue to run
after appscale-terminate-instances.

This may be related to this bug:

My question:
Is 'god stop' broken?
or is 'god' being used incorrectly by AppScale?
