#
# == Usage
#
# Extend an object and use it like a Mutex object:
#
#   require "mutex_m.rb"
#   obj = Object.new
#   obj.extend Mutex_m
#   # ...
#
# Or, include Mutex_m in a class to have its instances behave like a Mutex
# object:
#
#   class Foo
#     include Mutex_m
#     # ...
#   end
#   
#   obj = Foo.new
