[ns] Validation: flows_combined, flows_forced, flows_unforced

[Scott Ricketts]

I recently built allinone-2.30, and validation fails only on
test-all-red. The problems are in flows_combined, flows_forced, and
flows_unforced. The *.test files for each of these subtests are not
even close to their associated refs; instead, they are the same as the
red_twowaybytes ref file. Is there an obvious solution here, or should
I look deeper into the source code?

I am running on Ubuntu Linux 6.10, Pentium 4. I posted my test and
reference output at www.cs.ucsd.edu/~srickett/ns.

Thanks,
Scott
