Because the function wants to figure out how long time that has elapsed and
then deduct that time from the 'timeout' variable. If set 'now' before the
loop, we will detect more and more than was actually spent for every lap in
the loop.

The reason for this problem is of course that it often takes less than 1000ms
and since we count the timeout in full seconds, we often deduct zero from the
timeout value... To fix this, we should probably count the timeout time in
milliseconds in that loop.
