require 'rainbows/fiber'
# Simple Fiber-based concurrency model for 1.9. This spawns a new Fiber
# for every incoming client connection and the root Fiber for scheduling
# and connection acceptance.
#
# This concurrency model is difficult to use with existing applications,
# lacks third-party support, and is thus NOT recommended.
#
# This exports a streaming "rack.input" with lightweight concurrency.
# Applications are strongly advised to wrap all slow IO objects
# (sockets, pipes) using the Rainbows::Fiber::IO class whenever
# possible.
