CTS throws StopIteration exception after submitting correct solution

[GoogleCodeExporter]

After the user submits a correct combo and presses Select twice to send, it 
appears that the message is received by the MS, and the response to that 
message causes the CTS to crash.

Here is some log output showing the crash:

• Added labels: Component-CTS

Problem was caused by a generator function being used to implement a timer.  It 
would count down until it was done, but was not reset at that point.  The next 
call to the generator function would raise a StopIteration exception, which was 
not being caught.  Changed the code to reset the timer when it reaches 0.
