Yes. For exampe something like:

  perf stat --repeat 10 --pid $(pidof firefox) sleep 1

Should show firefox's resource usage sampled over 10 seconds.

If this doesnt work it should be fixed. Plus i suspect we should allow:

  perf stat --pid $(pidof firefox)

to run until Ctrl-C - like perf record allows.
