Looks a bit stupid. But I'd guess it's related to Thunderbird being  
configured to download mail when reading it and it treats setting  
\Seen the same as reading it. Just a guess though.

Sure, it would be possible. Also if Thunderbird really wants to fetch  
these messages' bodies, it could have done it using a single command  
instead of 20 separate ones..
