# Ruby Thread Pool
# ================
# A thread pool is useful when you wish to do some work in a thread, but do
# not know how much work you will be doing in advance. Spawning one thread
# for each task is potentially expensive, as threads are not free.
#
# In this case, it might be more beneficial to start a predefined set of
# threads and then hand off work to them as it becomes available. This is
# the pure essence of what a thread pool is: an array of threads, all just
# waiting to do some work for you!
