After examining the /paris/u4/ code and the /paris/sys code, it appears
that this bug is not present it our kernels.
It is fairly hard to be sure, since the abstraction layers move stuff
around, but the (apparently) critical section, setting the file offset
and the uio offset, seem to be properly set in the SUN kernels.
cf. sys/sys_generic.c, sys/vfs_vnode.c, sys/vfs_io.c, ufs/ufs_vnodeops.c
