Not until usb-2. There's work in progress for this issue. OpenBSD solved it
last year, by refactoring all the locking for mounts if I recall correctly.
It's harder in FreeBSD.
I doubt this will hit the 7.x tree, but it might happen.
I looked for status on this project, can't seem to find it atm.

and never get to the software part.
