    sfmiddleman sits in the middle as a compute-intensive proxy.  sfsender
    sends the middleman n "messages" each composed of m "blocks", and can
    pause for t1 and t2 times at microsecond granularity after each block send
    and msg send.  sfmiddleman reads blocks and does operations on them
    (default is decrypt/encrypt, can also do only encrypt), then forwards them
    to all connected receivers.  You guessed it, sfreceiver connects to
    sfmiddleman and reads blocks and prints timestamps.  For each op on a
    block, sfmiddleman notes the number of microseconds taken by the crypto
    ops, and the timestamp when it/they finished, and prints those.
    
    There is one known bug.  I'll fix it in the morning.  If there are others,
    I'll get them then too.
