[issue13396] new method random.getrandbytes()

[Raymond Hettinger]

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:

The differential cost of generating n random bytes is negligible compared to actually doing anything with the bytes once their generated.  

This optimization is close to being a total waste (saving 15 milliseconds for the abnormal case of generating 1 million random bytes).
