Thinking more about it, inf GC will only work as a runtime option for 
programs that don't consume too much memory. Compiling parrot or Rakudo 
with inf GC only will certainly fail. But it should be possible to get 
similar behavior to inf GC by tuning the GC memory thresholds. So ignore 
my concerns about inf GC.
