Following up on my own previous e-mail... I tried the following:

So the PIDs seem fine (?) - a new dccifd process (10153) is started when 
I connect to the dccifd smtp server. This process immediately exits upon 
quit. I don't know if that's the expected behavior. I also don't know 
what PID 5450, 5451 are doing as they don't seem to be used.
