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).

the following options turn on generational GC

  GC_enable_incremental ();
  GC_time_limit = GC_TIME_UNLIMITED;

with this, I get (very) slight performance improvement. For the 32mb tree test, BGC is 40% slower, for the 128mb tree, it's 31%

(disregard the previous figure of 23 %, it was an error in calculation, it should have been 33 %)
