Shawn, Everything's working fine, you just tripped over a variable access synchronization issue. In ~Foo, you decrement the variable that is being used as a loop counter in Main, and that screws up the loop counting as C# fully re-evaluates the condition at every loop.
Insert the line "int iter = iterations;" just before the loop, then use iter instead of iterations as the loop counter -- now the output counts down to zero. Not defining ADDSTREAM probably just caused the collector thread not to get any cycles before the loop was finished, hence the counter couldn't be manipulated.
