If we go down that path, we have to come up with a way of feeding that 
information to guest userspace.  Patches welcome.  If we meanwhile assume 
entropy == #bits, it fits the current /dev/hwrng model, and we can add an 
entropy count later if we want to change that.

I'll change my lguest implementation to suck from /dev/random, since noone 
else seems to consider its depletion to be a real issue.  It's no worse than 
what any other process can do.

Thanks,
Rusty.
