[zeromq-dev] Non-contiguous message thoughts

Here you go! The first test is attached. It does zero-copy transfer. Run 
it like this:

./local_lat tcp://192.168.0.111:5555 1000000 100

&

./remote_lat tcp://192.168.0.111:5555 1000000 100

Try it for 1, 2, 4, 8, ..., 256MB messages.

Adjust number of roundtrips in the test so that each test takes at least 
some time (couple of seconds). For very large messages there's no point 
in running for extended periods of time so decrease the roundtrip count 
accordingly.

Copy version of the test will follow shorty.

Thanks!
Martin
