+ For ARM we reserve FIQ for the Debug Agent Timer. We don't care about
+ laytency as we only really need the timer to run a few times a second
+ (how fast can some one type a ctrl-c?), but it works much better if
+ the interrupt we are using to break into the debugger is not being
+ used, and masked, by the system.
