void _next_idle

char _onewire_poll

(

void

)

The reason for splitting onewire_poll() into two functions (and for the OS_task attribute) is that otherwise, AVR-GCC will use a heap of registers to put all my debugging constants into separate registers before entering the loop. That is completely unnecesary and eats a lot of time.
