yes, should have specified that, sorry

i disagree that this is a good solution; similar to your haveged 
suggestion, this is a workaround.

Unless a program specifically uses randomness, it should not need to 
read any entropy. For the python runtime itself, this is preventable by 
setting fixed PYTHONHASHSEED. For `random` module, there is no clean way 
to prevent it.
