What do you mean by latency?  How are you measuring it?

Pure latency isn't bad.  We can correct for it.

There is/was some code in the kernel that would flap an output pin in the PPS 
code.  If that works, we should be able to measure something with a scope.

Maybe that would work better with 2 output pins: one before grabbing the time 
and one after.

These are my opinions.  I hate spam.
