AFAICS there is no code that enforces the 179s restriction.
And why are you using a separate wallclock timer instead of the sample
count? Does the higher resolution result in a noticeable improvement?
How should userspace detect streams whose sample clock is not
synchronous with this wall clock, such as digital inputs?
