> Currently, Crunch blocks and materializes PCollections (through foo.materialize()) and
PObjects (through foo.getValue()) on demand, but it would be a significant performance improvement
if we could mark several of these objects as to be materialized, and then materialize all
of them in parallel as part of a pipeline.run() call.
