    @cloud-fan, any idea how much memory is allocated for running sbt? 
currently one of my newly introduced tests fails on OOM during kryo 
    it's actually a bit weird as this is the test that stores it in memory 
deserialized objects, notice that the test doesn't really generate a true 2GB 
large dataset as the iterator returns the same array on every `next()` call, so 
basically the underlying buffer(actually buffers as it used chunked byte 
buffer) used by kryo is the first materialization of such a large piece of data.
    sbt execution of this suite seems to stop on the first error so I can't 
tell if the 'memory deserialized' version of this test would have passed.
    please advice, is it possible to increase sbt's process heap size? or 
should I remove/comment/ignore these tests?
