Bring WINDCATCHER back please!

[Edward Edgemenace]

So, just what sort of lag should affect one thread but not the other? The two boats were not sailing divergent (nor convergent) courses - they proceed the entire way in parallel.

I expected the test to come out even, since it is obvious that windcatcher is broken. I did not expect it to slow my "fast" pirate down, as it did in that (and a couple other) tests, with varying degrees of slowness induced.

If you devise and execute a better test, please share the results.
