That (and a message in syslog) would be just fine. ("Windows does it, so 
it's normal".) I know (and I think other USB drive users know too) that 
I need to wait for the little LED on the device to stop blinking before 
unplugging it.

IIRC, Windows mounts removable drives with write caching disabled, so it 
should probably be the same in FreeBSD.
