Right now pef-record can only do only 1 process or 1 thread. I started
working on a patch to support multiple of both (e.g., allow multiple -t
or -p arguments), but I have not finished it.
Other options: Arnaldo recently added a uid option or you can record for
all processes and filter the output to just your processes/threads of
interest.
