Indeed. I normally give it ten seconds, and that's it.

This is most likely due to a glitch found in most daemons that try to 
clear their state entirely rather than just running themselves through 
execve() and letting the kernel do the cleanup; Most likely, some 
variable somewhere is not getting cleaned up, so this is causing your 
problems.
