Wrap rand.Reader in a bufio.Reader.
rand.Read() results in a syscall to the host on every call instead
we can wrap it with a bufio.Reader to buffer and reduce number of syscalls.
This is especially important for TCP where every newly created endpoint
reads random data to initialize the timestamp offsets for the endpoint.
