# Generic connection pool class for sharing a limited number of objects or network connections
# among many threads.  Note: pool elements are lazily created.
#
# Example usage with block (faster):
#
#    @pool = ConnectionPool.new { Redis.new }
#    @pool.with do |redis|
#      redis.lpop('my-list') if redis.llen('my-list') > 0
#    end
#
# Using optional timeout override (for that single invocation)
#
#    @pool.with(timeout: 2.0) do |redis|
#      redis.lpop('my-list') if redis.llen('my-list') > 0
#    end
#
# Example usage replacing an existing connection (slower):
#
#    $redis = ConnectionPool.wrap { Redis.new }
#
#    def do_work
#      $redis.lpop('my-list') if $redis.llen('my-list') > 0
#    end
#
# Accepts the following options:
# - :size - number of connections to pool, defaults to 5
# - :timeout - amount of time to wait for a connection if none currently available, defaults to 5 seconds
# - :auto_reload_after_fork - automatically drop all connections after fork, defaults to true
