PS3, Line 587:     poll_backoff_ms = std::min(poll_backoff_ms << 1, 1000);
No big deal, considering it's already merged, but in general I think these 
kinds of changes are not improvements:
- as you pointed out, every compiler out there already makes such optimizations 
when it's safe to do so
- in this case, it's logically supposed to be "doubling", not a bitwise pattern 
that we're trying to express
- this isn't a hot path, so even if it were a valid micro-optimization, it 
wouldn't matter.
