This sounds to me as if you are Suffering From Buffering, possibly connected with a bad use of the .Peek() method. I presume that the .Peek() method will return a false value whenver no data is available from the filehandle, that is, whenever you are reading too fast from your child. I don't see any mention of the .Peek() method in the System.Diagnostics.Process.Standardoutput Documentation, but it also mentions the buffering issues you're likely to encounter.
