As Josh wrote, it's expected. The problem is known to exist for a long time already (probably as long as FreeBSD itself exists), and if there was an easy solution, certainly someone would have fixed it. Just remember to always umount first, and you're safe. In the early 90s I panicked a FreeBSD machine by removing a floppy disk that was mounted. I did that mistake only once -- afterwards I always remembered. If you have problems remembering, another work-around is to use the auto mounter daemon (amd(8)). It umounts file systems automatically that are not in use. Another nice feature of amd(8) is that you don't have to mount the file system either -- Simply plug the USB stick in, then access it, and amd(8) will automatically mount it for you.
