Too complicated, Derek!
Ignacio, just let pd consume 147% of your cpu, stuttering merrily, and
the output of writesf~ will magically be glitch free. Pd works on a
logical clock, it hardly knows what "real" time is
For example, I've rendered videos in Gem with sound this way, Pd
consumed ~10x my available cpu/gpu power so it took ~10x realtime to get
the output, but at the end it was all in sync.
