[net-perf] bwctl testing

[Michael Van Norman]

The path is the same is each direction.  I'll run a few test from UCLA 
to UCI and Abilene in a bit and post them.  A bug in the interaction 
between iperf and bwctl loses the results when originating some test 
from and I need to track it down and fix it.  In case anybody else has 
seen it and has a solution, the temporary file that iperf writes its 
results to is being truncated (i.e. the full results don't actually make 
it into the file).
