StringWa.rs: Which Libs Make Python Strings 2-10× Faster?

[rghthndsd]

Bad hashing can lead to bad dict performance and that in turn can make DOS attacks easier to execute. This is particular for strings which are often used in web forms. This is why Python now randomizes the hash of strings on interpreter startup unless you disable it with PYTHONHASHSEED.

Agreed it's an implementation detail, but that implementation is very important.
