I'd like to remind people of the possibility to make an engine module.

Rich... At the cost of being argumentative, why is there no need for it?

I had to install an entropy gather on Debian desktop because reads to
/dev/random would fail on occasion when the device was opened
O_NONBLOCK. I was not hitting it hard - I was just trying to grab a 32
byte one-time seed to seed an in-app generator. It was really
surprising to see Debian's RNG could only supply 7 bytes or so. I was
amazed it happened out of the box in 2014.

After that, I switched to alternate methods to grab any entropy I
could get my hands on, including things like EGD, HAVEGED and even
sensor readings on mobile devices (if they are available).

Thanks for the info.

One possibility is to have a separate program use prngd and write it to a 
RANDFILE that openssl uses.  Probably servers are the most important users, and 
you could/should have one file per server ...
