Well, even post 2.5.0 won't have the string provided in -B appended.  I 
can think about that as an add-on, but my initial reactionw oudl be to 
not make the change. Post 2.5.0 the interim results follow the output 
format - if one specifies a test-specific -k they will be keyval, 
test-specific -o will cause them to be csv, -O will retain the "human" 
style.  If the goal was to grep the different streams out of the interim 
results, the -B text would have to be added to each keyval emitted, 
which isn't really practical.

It is probably much better to direct each individual netperf's output to 
a distinct, suitably named, file.  That is what 
doc/examples/runemomnidemo.sh does.

happy benchmarking,
