But please, relax about performance, we still haven't run any meaningful

btw, is there any news on this patch? I'm quite keen on dumping
LilyPond's Rational class in favor of Scheme rationals, but adding gc
mark functions for that is just too much work; BGC would be a nice
soluiton to this.
Well, no real news. My "not-so-meaningful benchmarks" (running a
loop[*]) reproductively show that "GBGC" is noticeably slower than "real
Guile" (1.5 to 2 times slower).
tuning down GC_free_space_divisor to 2 sped things up a little bit,
around 10 %. I'm now at 77sec (vs GUILE 1.8: 52 sec)
I'm on dual-core nowadays, so real time it's actually still a bit
faster, as BGC is multithreaded.
