Volk is fine, I think its an indication that the getclocktime monotonic
is not working correctly, or I have some bad math involving the time.
Thats just an assertion to check the the total time port i was idle was
less than the total time the object has been in existence. Seems like a
sane thing to assert on.

For the quick fix, its totally fine to comment out that line.

I wonder if clock_gettime(CLOCK_MONOTONIC, &ts); is working for your system?

And can you tell me what OS and version are you using?
