Joel Dice	8e5ce11047	refactor memory management code ... We now support immortal objects, which the GC will scan for references but not consider for collection. On x86_64, we allocate JIT code memory via mmap, which lets us map memory into the bottom 2GB of the address space, ensuring that 32-bit relative jumps and calls work.	2008-01-09 18:20:36 -07:00
