 Todo:
+- [ ] Raise Bindlib and Outcome on Travis and Appveyor as they regressed!!!
+- [ ] algorithm::atomic_append needs improvements:
+  - Trap if append exceeds 2^63 and do something useful with that
+  - Fix the known inefficiencies in the implementation:
+    - We have an extra read() during locking between the scanning for our lock
+    request and scanning for other lock requests
+    - During scan when hashes mismatch we reload a suboptimal range
+   Loses SMB and NFS compatibility:
+    - We reload header when a memory mapped header would be much faster
 - [ ] In DEBUG builds, have io_handle always not fill buffers passed to remind
 people to use pointers returned!
 - [ ] Port AFIO v2 back to POSIX

 - [ ] C bindings for all AFIO v2 APIs. Write libclang parser which autogenerates

+  - Could speculatively map 4Kb chunks lazily and keep an internal map of 4Kb

 - [ ] Rewrite correctness test in benchmark_locking to use mapped_file handle.
