It already defers the worst of the work of actually mixing in the
samples, but it would be feasible to defer the delta calculations too.
The estimator is pretty much known to be bogus anyway, and represents
the majority of the work presently done here.  I wouldn't miss it if a
gig-E just assumed one bit of entropy per sample, or even per sample
batch.

Rui, as a first part of the testing, please measure with entropy
estimation on and off (rndctl -e/-E).  That will guide any next steps.
