I think it would better if most of the tests could be run in parallel, so
that we could run it on different interfaces as well. That would require,
more work in the library, at least, removing 'pkill netstress', making
the tests to be self-contained. There are also other options with using
netns per test or a group of the tests.

Assuming those test are using different interfaces just to load the
machine more, the tests should be rewritten to use a single interface.
