+- Unmonad `mmap` (@dinosaure, #454)
+  `mmap` is a _syscall_ which does not block. The ability to use it outside
+  the scheduler monad (like LWT) permits us to _detach_ multiple processes
+  to analyze a PACK file.
+
+  With this PR, we take the advantage of `Thread` or `Lwt_preemptive`
+  (or more acccurately, the concurrency) to analyze a large PACK file and
+  speed-up the `clone`/`fetch` process.
+
+  The distribution comes with a new binary, `carton.verify-pack` which is
+  `git verify-pack`.
