>             Fix For: 0.7.0
> There are a number of performance issues with locks and memory pooling:
>   - Locks are not allocated on cache-line boundaries and suffer from 
> false-sharing issues.
>   - The extra lock checks (checking the acquired state) cause significant 
> overhead.  These should be removed.
>   - Pooled memory objects are not cache-line aligned and suffer from 
> false-sharing
>   - Memory pool statistics are useful but costly from a performance 
> standpoint.  These should be able to be optionally disabled.
