A config snippet could to do this, but what I think could be added which would make this a great failsafe feature is an automatic timer to abort the reload at 9 ¾ minutes if Cirrus still has communication with the system. If it was a button on top you could just press it, get to work and go on like normal with no worry about locking yourself out of a system that is 2 thousand miles away. It also fixes the user error of not stopping the reload in time.
#reload in 10 "failsafe"
#(9 min) -- no saving of the file in this period --
