Streaming test is pretty fragile

[hmaarrfk]

The streaming test makes many crucial assumptions:

1. It assumes streaming channel pairs are in loopback configuration. Nice for a first test, poor to help others...
2. It starts reading, then starts writing. This is fine, except that reading has a finite timeout. It seems to spin for a bit before stopping. The second assumption is that writing will start in this short period of time.

Finally, even if nothing is written, the test says "success". Great!!!!!!
