To quickly summarise that, the convolution engine uses multiple CPU
cores when they're available, but the way in which it does this is
designed for realtime operation, and can fail when running in
freewheeling mode. From what I understand, it's likely (but not
guaranteed!) to work on single-core systems, but on multi-core systems,
it often (but not always) fails.

FWIW, with the performance I have on just one of my CPU cores, I'd be
quite happy to have the convolution all run on one core if it meant that
freewheeling mode worked reliably.

Thanks
