When running this code, it takes around 1440 seconds on my PC. Then I modified the stack management routine to re-use available stack frames (and conses), instead of creating new ones on every call. This took execution time down to around 1240 seconds. A good improvement, I'd say. However, with the change described above, stack frames won't ever become garbage anymore. My question is: does the loss of GC-ability outweigh the performance gain?
How many frames will then hang around? If I make a deep call, and never do another deep call, will I then have frames lurking around from the deep call?
