I rebased it.

Fixed.

I didn't change it because I think those who don't expect any failures using a
well designed script may not need details of failures. I think reporting such
details will be required only for benchmarks where any failures are expected.

OK. I fixed printVerboseErrorMessages to use a static variable.

I fixed to declare the variables in the case statement blocks.

fixed.

Ok. I made a new function "discardUntilSync" for the pipeline cleaning.

I fixed to report both serialization and deadlock failures always even when
they are 0.
