We only have a few storage drivers left that use Giant and twe(4) is one of 
them.  I don't have any hardware to test with, however.  I have verified the 
patch compiles, but I'd appreciate it if some folks with twe(4) hardware could 
test it.

The patch is at http://www.FreeBSD.org/~jhb/patches/twe_locking.patch
