We're using bufio to batch reads of /dev/urandom to 4k, but we weren't doing the same on newer platforms with getrandom/getentropy. Since the overhead is the same for these -- one syscall -- we should batch reads of these into the same 4k buffer. While we're at it, we can simplify a lot of the constant dispersal. This also adds a new test case to make sure the buffering works as desired.
