>
> One of the challenges of debugging GC issues is that it can take a long time
> to reproduce GC pauses. Isolating the LRU block cache and benchmarking it
> independently can more easily cause measurable and reproducible GC issues.
> In addition, making sense of the noisy GC logs is difficult.
> This may not be for commit, but I wanted to share some code and scripts I've
> written to tackle these problems.
