Re: "The device _______ is being ejected. This may take some time"
I'd wager you have package notify-osd active. For some reason, Thunar prefers xfce4-notifyd to display notifications about ejected media. If notify-osd is installed, Thunar will display your popup dialog, which never disappears. The notification bubbles generated by xfce4-notifyd do go away once the media is safe to remove.
You should try to remove notify-osd and install xfce4-notifyd, then reboot. To configure the Xfce notification daemon, run xfce4-notifyd-config.
