I'm going to have to time how long it takes for a remount to take place. There may be different defaults on Slack then there is on Fedora.
Edit: Interesting, I think that in Fedora KDE the problem is fixed. It's not remounting itself. I bet anything that is was the Gnome 2 DE in Fedora 14 that was causing the problem (Or maybe it was just Fedora 14). So, since I started running Fedora 15, I've been rushing to remove the usb stick before it remounted, and, I didn't have to. I'm glad I found this out.
