Very cool! I've had lots of ideas around how Elixir would be great for building orchestration or provisioning tools. The concurrency model and immutability are fantastic for that kind of work. Regarding system calls and concurrency: Erlang does lots and lots of system calls. I think what that/those person/people were talking about are NIFs (Natively Implemented Functions) written in C. Those block the scheduler while calling out to C. However, that is a thing of the past with the implementation of dirty schedulers. AFAIK, Erlang/OTP 18 added better control of dirty scheduling and I think version 19 builds on that some more.
