The changes are now a bit more succinct with less code changes required.
Behavior is tested a little bit more thoroughly and a memory problem
when reading incomplete lines was fixed. ReadHeader also always directly
returns if header reading failed.
Error messages now are back to what they were before the change, if the
new behavior is not used.
I also tweaked the documentation text a bit.
- Generally increased the time allowed before they timeout.
- For tests w/ a clear termination condition (most of them), made
timeouts result in a test failure.
- Seemed to be a race in some cases between tests generating output and
the input reader stream getting removed/closed, so moved stream removal
closer to termination time, when all output should be available.
