The bcopy() of fields from the old vmspace to the new vmspace in vmspace_exec() is mostly wasted effort. With one exception, vm_swrss, the copied fields are immediately overwritten. Instead, initialize these fields to zero in vmspace_alloc(), eliminating a bcopy() from vmspace_exec() and a bzero() from vmspace_fork(). END
