File tests/query_test/test_spilling.py:

Line 66:     and therefore will not reliably pass with the deny reservation 
debug action enabled.

I guess there are two reasons: one are the tests where scratch_limit=0, where 
that's just the nature of the test.

The second is the build side limitation. I filed IMPALA-5834 for that. It's 
unclear how important it is but it seems worth noting. There's a similar issue 
if there's a large number of duplicate values as well. I think both boil down 
to doing a spilling nested-loop join.
