# {NeverBlock}[www.espace.com.eg/neverblock/] library that combines
# the EventMachine library with Ruby Fibers.  This includes use of
# Thread-based Fibers under Ruby 1.8.  It currently does NOT support
# a streaming "rack.input" but is compatible with everything else
# EventMachine supports.
#
# === :pool_size vs worker_connections
#
# In your Rainbows! config block, you may specify a Fiber pool size
# to limit your application concurrency (without using Rainbows::AppPool)
# independently of worker_connections.
#
#   Rainbows! do
#     use :NeverBlock, :pool_size => 50
#     worker_connections 100
#   end
