Stats overhead due to hitting the clock and pulling a mutex caused a massive slowdown so now work is assigned to a new queue only when the candidate queue is deeper than the average of the other queues and threads are created only when the depth of the queue is larger than the number of threads working on that queue.

Worker threads come and go as needed with a lower bound of 2 and an
...
upper bound of ASYNC_NIF_MAX_WORKERS. Stats were improved to use
thread local storage for measures. With stats working again wterl
uses them to determine who to evict. Wterl's signature calculation
for an operation wasn't correct and so the cache wasn't efficient at
all, this has been fixed.

WIP: simplify the cache from hash-of-lists to list; use a CAS() operation to protect the most-recently-used (mru) list.

Add a bit of statistics tracking for two reasons, a) to help inform
...
where a request should be enqueded and b) to track request latency.
