    I'm reverting the various changes to the throughput test programs since as far · c980820d
    Pieter Hintjens authored
    as I can see, these didn't work any more. At the very least, the command line
    API was broken and forced the user to enter new, exotic arguments. Patches
    should not break existing APIs. But also, the internals of these programs had
    become weird.
    
    If we want to build more complex performance tests, that's fine, but we should
    make new programs, not break the old ones. We need minimal, safe performance
    tests in 0MQ.
    
    Also, the code was quite horrid. So it's gone. If anyone wants to bring it back
    please make the code neat, and build new APIs instead of breaking the old ones.
    
    Cheers
