> Streaming seems to be broken in dotNext. There are several tests that are
> failing.
> The results from C below produce clean results.
> The results from D which are streamed through CMD produce control characters
> on some of the output.
> define CMD `perl GroupBy.pl '\t' 0`
> ship('/homes/monster/pigtest/pigtest_next/pigharness/dist/pig_harness/libexec/PigTest/GroupBy.pl');
> A = load '/user/user1/pig/tests/data/singlefile/studenttab10k';
> B = group A by $0;
> C = foreach B generate flatten(A);
> D = stream C through CMD;
> store C into '/user/user1/pig/out/user1.1321117428/ComputeSpec_7_C.out';
> store D into '/user/user1/pig/out/user1.1321117428/ComputeSpec_7_D.out';
> Other streaming tests that fail with control characters:
