[issue40611] Add MAP_POPULATE to the mmap library

[STINNER Victor]

STINNER Victor  added the comment:

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!

[issue40611] Add MAP_POPULATE to the mmap library

[Ethan Steinberg]

New submission from Ethan Steinberg :

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.
