[GitHub] [arrow-julia] TanookiToad commented on issue #336: Invalid argument error

   I forgot to ```copy``` the mmapped table in my sample code. 
   
   As @jeremiedb mentioned, you can overwrite the loaded arrow file on Linux if it's copied, but the same code will raise an error on Windows. A temporary workaround from [JuliaData/CSV.jl#170](https://github.com/JuliaData/CSV.jl/issues/170#issuecomment-365259677) is to use ```GC.gc()``` before saving it.
