But alone of all of these, garbage collection still remains just as costly to implement as ever. That should tell you something about how poorly it matches the characteristics of modern computing hardware.
So maybe we need to redesign the hardware. Perhaps reference counts could be stored in their own special area of memory, updated in parallel with main memory accesses so that they don't slow anything down. Make it multiported so that all your cores can access it at once without locking. Maybe even build it out of counters instead of registers, so there's no data bus, only an address bus and inc/dec control lines. -- Greg -- http://mail.python.org/mailman/listinfo/python-list
