I wrote a NIF which have function that can take a long time to run. To prevent the scheduler from being overloaded with long running functions (even if marked at dirty), I made my NIF threaded and it sends message back to erlang using enif_send.

I want to make those call synchronous from a “programmer point of view”. Similar to a Process.sleep() call.

I was wondering what was the best approach. To avoid messing with the caller message inbox and to have an isolated process to receive the message, I thought of using something like this:

task = Task.async(fn -> 
call_nif(self()) 
receive do 
<wait for nif response> 
end 
end)
Task.await(task)

Would that be a good approach?
