Here is another patch that keeps the re-seeding in place, just moves 
the selection of the preferred random number generation method into a 
single module:

(Note that I have removed some special "randomness" code for CSRF 
handling as it seems strange to handle that in a different way than 
gen_sid/gen_nonce in client.py; ideally, we would have a strong random 
number generator anyway if we care about these things).
