I accidently encountered failed tests in this part

InMemoryDatasets.jl/test/join.jl

Line 811 in 4220d4b

dsl = Dataset([[Characters{1}(randstring(1)) for _ in 1:10^5] for _ in 1:3], :auto)

I cannot reproduce it, however, it must be checked - e.g. make sure that it is not related to data race.
Perhaps, it is due to cumsum!???

The problem is related to having mis-matched pool and refs in the output data sets.

I changed cumsum!, and ran the package tests 400 times to make sure every thing is ok, however, keep it open for further investigation.
