ee60d48cfe fix subtle bug in hashMapInsert which caused us to update the old array previously associated with the hash map, whereas a GC causes the table to be resized when a weak reference is removed and thus a new array used 2008-01-19 13:12:16 -07:00

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.
