 When I solve problems using Dippy and Dip with doPriceCut set to 1 I get
 the following kind of output when generating columns:

 not parallel: cosine=0.899229
 not parallel: cosine=0.53936
 not parallel: cosine=0.753778
 not parallel: cosine=0.753778
 not parallel: cosine=0.348155
 not parallel: cosine=0.696311
 not parallel: cosine=0.928414
 not parallel: cosine=0.899229

 It seems like the default time limit given when solving subproblems with
 Cbc is not set correctly? I did get rid of this output in the past, but
 only by changing DIP source code. Is there a better way?

 Regardless, the not parallel always occurs.

 I’d like to get rid of these two output statements and only leave the

 Alps0240I Processed 20 nodes, has 4 nodes, best relaxed 2.33333, best
 feasible 5

 statements.
