That may be so, but Timo claimed the opposite (as I read his response). I'm 
merely pointing out that I cannot see the behavior that Timo states. If you 
want to get rid of all these processes you have to killall.

Can you elaborate on this? Also, have a look at the thread I mentioned. 
Dozens pop3-login processes were staying sleeping for 5 or more hours. There 
was no remote part anymore. Doesn't sound like they "terminated soon due to 
protocol design".

Yes. Right you are. And especially with ssh it's quite helpful ;-)

That concerns the "tidying up"? In my case it wasn't a problem with still 
occupied ports, I checked for presence of processes.
