Infinite timeout loops are hard to read. Refactor it
to plausible 'do {} while ()'.
Note, the supplied timeout can't be negative for current use,
though if it's not dividable to 10, we may go below 0,
that's why type of the parameter is int. And thus, we may move
the check to the loop condition.
No functional changes implied.
