Hello. I have encountered the following error when I tried to start remote workers with Clustermanagers. In 0.5.2 everything worked fine.  
ERROR:Unable to read host:port string from worker

```julia
fatal: error thrown and no exception handler available.

Looks like you have a very long username on that machine? [This pull request](https://github.com/JuliaLang/julia/pull/22457) has a fix.

@nalimilan, thanks! username is not that long, I have updated the files both on master and remote machine but unfortunately the error is still the same
