Basically if you're lucky you'll get the full rate by direct linkage of ekeyd
to the pool.  However, on a lower performance machine you're more likely to get
ekeyd operating 'bursty' and as such wasting entropy and not giving you the
full bandwidth.

The EGD stuff just introduces an elastic buffer and a proper monitor.  In
theory this could be directly added to ekeyd if an enterprising soul felt like
making an effort and supplying Simtec with a patch.
