Has division freeze bug

Every so often, this commit freezes in the 32-bit division function,
which, if I use "Set PC to cursor", returns to timer1_poll_delay right
after Timer1_Init().  Neither Timer1_Init() or timer1_poll_delay() have
any divsion.  However, the timer1_poll_delay_ms() that calls
timer1_poll_delay() has 32-bit division in its argument list.
