#203 Messing up display while message is loading

[lichtgestalt]

Recently Michael Phipps has entertained us with some massive OBOS cvs
commits which generated accordingly long cvs digest mails. These mails
are sometimes 300k-500k long and take some time to load on my system.
You can watch the scrollbar knob shrinking while it loads and the
reader thread of BeMail is churning away.

While the message is loading, click with the mouse into the message
and if necessary move it a bit up and down. You'll see some funny
effect like scrolling through the mail.

One time, I did a Shift+Alt+W to close the mail leaving the status
"New" and had the follwing crash of BeMail. I don't know if it has
anything to do with it or if it was just bad luck:

Big mail, closing without changing status
