## thread-pool.rb
require 'thread' # for Mutex: Ruby doesn't provide out of the box thread-safe arrays

# NOTE: Modifications from original:
# => 1. The instance variable @running_threads has been removed, because
# =>    the size of this array never decreases.
# => 2. Did not need the #await_completion instance method
# => 3. Added a class method #wait_for_threads that accepts an array of threads
#       and joins them
