Jason Gauci commented on CRUNCH-320:
------------------------------------

Sorry for the delay, but I will try to test this out later this week.

If your patch fixes the test case that I posted, I'm sure it will fix our use case as well.

> 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.
