Summary:
In the hg sync job, we need to load up the ancestors for all bookmarks known to
the server we are pushhing to, and for e.g. fbsource that might be > 10K
bookmarks. If we fetch those 1 by 1 (because e.g. cold cache), that will take a
very long time.
Unfortunately, we don't currently have a way of buffering access to changesets,
so for now let's mitigate by buffering.

Mononoke is a next-generation server for the Mercurial source control
system, meant to scale up to accepting
thousands of commits every hour across millions of files. It is primarily
written in the Rust programming language.
Caveat Emptor
Mononoke is still in early stages of development. We are making it available now because we plan to
start making references to it from our other open source projects.
The version that we provide on GitHub does not build yet.
This is because the code is exported verbatim from an internal repository at Facebook, and
not all of the scaffolding from our internal repository can be easily extracted. The key areas
where we need to shore things up are:
Full support for a standard cargo build.
Open source replacements for Facebook-internal services (blob store, logging etc).
The current goal is to get Mononoke working on Linux. Other Unix-like OSes may
be supported in the future
