I run s7 Scheme in audio contexts (with Scheme for Max), which is quite similar (soft-realtime), and I've found the impact of the GC to be much smaller than I expected. I need to run things such that an extra ms of either latency or jitter does the job, because the GC runs are bursty. So running in an audio app, if the i/o buffer is more than few ms (latency) in size (the norm when amount of heavy dsp is going on anyway), the GC runs just happen in that latency gap, and timing is solid. Or alternatively, timing is off by a ms for one pass and correct on the next, either of which are fine for music.
