any updates?

I resolved the conflict. Good to go?

I think it's `__strong_reference` on FreeBSD, (and the order of arguments are different) here is a hack https://gist.github.com/iblis17/6f340863fbb233a9326b0c4cbf035746

Splitting file is .... infeasible for me. Since it require doubling disk space.

I just tried CSVFiles (don't know its existence before) ```julia julia> i = TableTraits.getiterator(iter) ERROR: OutOfMemoryError() Stacktrace: [1] #csvread#28(::Array{Any,1}, ::Function, ::IOStream, ::Char) at /home/iblis/.julia/v0.6/TextParse/src/csv.jl:77 [2] (::TextParse.#kw##csvread)(::Array{Any,1}, ::TextParse.#csvread, ::IOStream, ::Char) at...

Query failed, also ```julia julia> @from i in iter begin @select i @take 10000 end ERROR: OutOfMemoryError() Stacktrace: [1] #csvread#28(::Array{Any,1}, ::Function, ::IOStream, ::Char) at /home/iblis/.julia/v0.6/TextParse/src/csv.jl:77 [2] (::TextParse.#kw##csvread)(::Array{Any,1}, ::TextParse.#csvread, ::IOStream, ::Char)...

> I think CSVFiles is based on TextParse, and isn't probably using its feature of reading rows line-by-line. @shashi I read the doc about [`csvread`](https://juliacomputing.com/TextParse.jl/latest/index.html#Reading-CSV-1), but do not get how...

Also found this https://github.com/JuliaParallel/Blocks.jl But it looks unmaintained. Should I devote my effort to Blocks.jl?

By the way, please review my PR on Dagger.jl :)
