That will only work so long as timer 1 isn't being used to provide a 
properly randomised statclock, which it really should be made to do.  It 
would be better to build something based on timer 0, using the 
interrupt-pending bit and the hardclock handler to emulate the high-order 
bits of the timecounter.
