Things still TODO / TBD in this PR:
- **Why on extreme loads the new version has significantly worse tail
latency?**
- StringBuilderEncoder.DEFAULT_BYTE_BUFFER_SIZE (8k) effectively overrides
MemoryMappedFileManager.DEFAULT_REGION_LENGTH (32k), is that reasonable?
- Java 9:
- Buffer unmapping, as pointed here:
https://github.com/apache/logging-log4j2/pull/87#issuecomment-312488652
- WriteTouch should have an opportunistic impl based on VarHandles.
- Not doing stuff "in background" on 1-core machines; probably not doing
write touch on "small" machines (< 4 cores?)
- Cleanup and comments to the recently added write touch and background
stuff
