Bug 5280: Add ProgressTracker
ProgressTracker determines the tracking delay required
to keep the outbound queue reasonably full. Unlike Guava's
RateLimiter, we can assume cooperative callers, hence we
can use an enqueue-and-wait strategy as appropriate. This
lowers contention in multi-threaded access, as the wait
part of the cycle is spent outside the lock.
