This affects the -p, -t and -u options that previously defaulted to per-thread mmaps. Consequently add an option to select per-thread mmaps to support the old behaviour. Note that per-thread can be used with a workload-only (i.e. none of -p, -t, -u, -a or -C is selected) to get a per-thread mmap with no inheritance.
