# 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 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.
