I suspect it's normal after all, since it's running this:

    filter_stderr()
    {
      # Usage: filter-stderr EGREP_REGEXP 'command'
      regex=$1 cmd=$2
      (exec 3>&1; eval "$cmd" 2>&1 >&3 | grep -E -v "$regex" 1>&2)
    }
    ...
    filter_stderr "$mirror_re" "$mirror_cmd"

and ps is just showing the eval'd subshell and filter-running processes
with the name of the parent.
