So I changed the local port for the stream test from 8967 (previously used) to 8977 and the test ran […]

I just tried

``` log_set_print_timestamp(osmo_stderr_target, 0); ```

in `tests/stream/stream_test.c`

and got an immediate segfault (glanced at the code and I guess it's because the logging system isn't initialized by the test, it just uses `osmo_gettimeofday()` and custom macros for logging).

I could remove all the time logging instead from the macros defined in the test code. If that's what we want.
