Julia can't run in parallel mode: (ERROR: type LocalProcess has no field r_stream)

[mauriciogtec]

I installed julia 0.5.2 and 0.6-rc on WSL without problems and it runs fine in default mode. But when trying to open julia in parallel mode using

julia -p <#cores>

I get the following error

ERROR: type LocalProcess has no field r_stream

I am using Windows 10 creators update. I have tried installing Julia using PPA and generic Linux binaries, in either case I get the same error. This is a WSL issue, since I have tried this in a full Linux installation without issues.

@mauriciogtec - I guess... it might be a network problem because "Each worker binds to only one of the local interfaces and listens on the first free port starting from 9009. -- https://docs.julialang.org/en/stable/manual/parallel-computing/#network-requirements-for-localmanager-and-sshmanager "

You look like having working real linux system, so could check what port listen when launching julia parallel mode. Compair it with in WSL. I think... that port will not listen. If so, that might be similar to mine; oh... that's not a julia issue.

In my problem #1498 (comment), it looks like "Anti-Virus was blocking the program from listening", but in other issue #1853 (comment), that looks like to happen without Anti-Virus.

Mine hangs right after running cmdlineargs test. If I hit ctrl-c, I get an EXCEPTION_ACCESS_VIOLATION (not sure what the deal is with the path).

The same build makes it through Base.runtests on another machine. The only difference is the target architecture. I do have different anti-virus programs on the two machines, but most of the rest of the tests pass, and it's clearly using multiple workers right from the start.
