Justin,

i am not sure the syntax is correct
however its looking like perhaps you may be correct
in regard to the race condition

the Programming Ruby book provides an example of using mutex

require 'thread'
mutex = Mutex.new


count1 = count2 = 0
difference = 0
counter = Thread.new do
loop do
mutex.synchronize do
count1 += 1
count2 += 1
end
end
end
spy = Thread.new do
loop do
mutex.synchronize do
difference += (count1 - count2).abs
    end
  end
end
