But what is the cost of an miscorrelation? If the answer is $50 I suggest 
you should get a true real-time operating system like QNX or Linux with 
real-time extensions. You might see zero failures on a non real-time system 
in many hours of testing system but you can never know for sure.

If the remote device is also under your control I suggest modifying the
protocol to add some kind of ID in the poll that is echoed in the response.
