Some of the ptrace tests need to wait for a child process to become a zombie before preceding. The parent process polls the child process via the kern.proc.pid sysctl to wait for it to become a zombie. Previously the code polled until the sysctl failed with ESRCH. Now it will poll until either the sysctl fails with ESRCH (for compatiblity with older kernels) or returns a kinfo_proc structure with the ki_stat field set to SZOMB. END
