> The new unified memory management model in SPARK-10983 uncovered many brittle tests that rely on arbitrary thresholds to detect spilling. Some tests don't even assert that spilling did occur.
> We should go through all the places where we test spilling behavior and correct the tests, a subset of which are definitely incorrect. Potential suspects:
> - UnsafeShuffleSuite
> - ExternalAppendOnlyMapSuite
> - ExternalSorterSuite
> - SQLQuerySuite
> - DistributedSuite
