I think it is not `limits the maximum number of interpreters`, it is
`limits the maximum number of concurrently running paragraphs`. I have concern
that 65536 would be too large for single process to schedule and coordinate so
many threads. @mebelousov Do you see this issue in production ? Because
concurrently running 100 paragraphs would be a very busy zeppelin server with
many users. ---
