So I ran this with the large example and I see GC Warning: Failed to expand heap by 30635458560 bytes a few times (that's 30 GB, my laptop only has 8 GB!!) and finally warning: g_spawn_sync failed (0): gs: Failed to fork (Cannot allocate memory) Maybe exponential growth is not the best choice here? At least my system can't handle this score anymore. Also most of the 'speedup' by this patch seems to come from segments _after_ music interpretation (only 10% improvement in music interpretation, but around 2x for the total time). I think the later parts just benefit from the enormous heap because GC doesn't need to run at all? But that's not really the idea of this patch, is it? https://codereview.appspot.com/561390043/
