require 'thread'
# Spawns a new thread for every client connection we accept(). This
# model is recommended for platforms like Ruby (MRI) 1.8 where spawning
# new threads is inexpensive, but still seems to work well enough with
# good native threading implementations such as NPTL under Linux on
# Ruby (MRI/YARV) 1.9
#
# This model should provide a high level of compatibility with all Ruby
# implementations, and most libraries and applications. Applications
# running under this model should be thread-safe but not necessarily
# reentrant.
#
# If you're using green threads (MRI 1.8) and need to perform DNS lookups,
# consider using the "resolv-replace" library which replaces parts of the
# core Socket package with concurrent DNS lookup capabilities.
