- 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.
more cases.
It will now not only fire after table-reads have been completed,
but also after the last event of a whole-file-read (or whole-db-read, etc.).
The interface also has been extended a bit to allow readers to
directly fire the event should they so choose. This allows the
event to be fired in direct table-setting/event-sending modes,
which was previously not possible.
Generally tried to make them more reliable and execute quicker.
They all now load the listen script as a trick to make sure input
sources are fully read, but also terminate() at appropriate times
so that they don't take more time than needed. They're also all
serialized with the 'comm' group so listening on a port doesn't
interfere with the communication tests.
