    This issue (and corresponding pull request) adds MAP_POPULATE to the set of flags exported by the mmap module. This flag is incredibly handy for speeding up data processing and is available on most Linux systems.

    Thanks Ethan Steinberg, the constant is added to 3.10.

    Sadly, adding a new constant is a new feature, and we don't add new features to stable branches. The 3.9 branch no longer accept new features past the feature freeze which is over. In the meanwhile, you can hardcode the constant, but its value may depend on the platform, be careful!
