Make sure to read here about the threadsafety and strict clocking I worked in: http://pastie.org/215285
# Used to repeat a block at a given interval, in seconds.
# Repeat::Every 30 do
# puts "I will be printed every thirty seconds"
# end
# Can be told to not abide slow iterations, and continue on according to
# schedule regardless of the state of block-execute iterations:
# Repeat::Every 4 do
# sleep 5; puts "I completed after the next block was initiated"
# end
# Finally, some convenience methods are proffered for working with the seconds:
# Repeat::Every 2.hours do; end
# Repeat::Every 3.days do; end
# Repeat::Every 140.milliseconds do; end

# even if they exceed the allowed iteration time.

# Unfortunately, we can't do a metaprogrammy bit of magic here, due to the
# fact that blocks in 1.8 can't take other blocks as arguments. Hence, you
# have to do some lambda magic like this to use the singualar syntax:
# Repeat::Every.minute(lambda do
# puts 'whee'
# end)

define_method stretch do |proc|
::Repeat::Every 1.send(stretch.to_s + 's'), &proc

Loop a block of code every set interval:
Every.twenty.milliseconds { #stuff }
Every.second { #stuff }
Every.two.minutes { #stuff }
Every.twenty.four.hours { #stuff }
You get the idea..
