Creating and running >120 Celluloid::IO actors raises an error on MRI, even when doing NO I/O

gistfile1.rb

# Running on OS X
# JRuby + Celluloid = OK
# MRI + Celluloid = OK
# JRuby + Celluloid::IO = OK
# MRI + Celluloid::IO = Too many open files - pipe (Errno::EMFILE)

require 'celluloid/io'

class SimpleActor
  # include Celluloid    # Creating regular Celluloid actors works on MRI
  include Celluloid::IO   # Creating >120 (approx.) Celluloid::IO actors on MRI rasies Too many open files - pipe (Errno::EMFILE)

  def do_work(id)
    puts "[#{id}] Starting..."
    result = 0
    10_000.times do
      result += rand 1..8
    end
    result
  end

end

results = 1_000.times.map { |n|
  SimpleActor.new.future :do_work, n
}.each{|future| puts future.value }

The actual problem is with MRI, not Celluloid::IO: https://gist.github.com/Felixyz/5788375

The actual problem is not with MRI but with a low default limit number of allowed file descriptors on OSX (10.8.2)

@felixyz, i just came across this (obscure) error. have you found any other solutions? i'm looking for a way to terminate existing Celluloid actors without having to raise the open files limit on the system.

@nicksoto @felixz did you a find a solution for this?
