"i" should be an int here because we are trying to use it to count
to 10000.  The original code looks like it could hang in a forever
loop.

If we exit the loop via a timeout, that error isn't handled.  Should
we limp along, or return an error?

Dan,

Thanks for this part. After another look at this routine, there are a couple of 
places that need to be fixed. I will take care of that.
