It appears that current iteration of freeverb~ is susceptible to denormals
bug. Namely, feeding silence after sound hogs cpu (I chuckled by reading
Pd's CPU footprint which was in excess of 400%). Adding a tiniest amount of
DC bias inside Pd solves this but I wonder shouldn't this be simply added to
the freeverb c code instead?
