An inline comment prefixed by a space doesn't mean the space
is dropped, and sleep(1) will get a blank in its argument.
Move the comment on its own line.

With recent improvements, we're not CPU-bound at all while testing
UDP performance. Give the VM more memory and CPUs, forward two
additional ports, start up to four threads in parallel, and give
single iperf3 threads higher bandwidth targets.

Based on a patch from Giuseppe Scrivano, this adds the ability to:
- specify paths and names of target namespaces to join, instead of
a PID, also for user namespaces, with --userns
- request to join or create a network namespace only, without
entering or creating a user namespace, with --netns-only
- specify the base directory for netns mountpoints, with --nsrun-dir

they're not created, implemented --netns-only and --nsrun-dir,
updated pasta demo script and man page]
