JuliaLang/julia — Issue #463: HashTables not being successfully fetch()'d when run on other processors

Attempted to write a basic parallel word-count program while playing with Julia's parallelism. See https://github.com/ajdecon/julia-wordcount. To duplicate, run "julia -p 2 testrun.j" using the files in this repo.

When I @spawn the wordcount function (which returns a HashTable) to a second processor and then try to fetch() the result, I get a de-serialization error.

Message from @JeffBezanson suggests that the problem is the lack of custom serialize/deserialize methods for HashTables.

See this thread in the julia-dev list for more details: http://groups.google.com/group/julia-dev/browse_thread/thread/6aad0d71691e9d4c.
