(slow_pid_reuse): New function to grab last 'n' pids to prevent pid reuse. (fork_parent): Move last_fork_proc into slow_pid_reuse. Handle fork_pids debugging. Eliminate unnecessary call to set_child_mmap_ptr. (fork_init): New debugging function. * mmap.cc (fixup_mmaps_after_fork): Renamed from recreate_mmaps_after_fork. Rely on copied data after a fork.
