Valgrind vs --profile

dogbert@dogbert-VirtualBox ~/repos/rakudo $ ./perl6-valgrind-m --profile -Ilib t/spec/S03-junctions/autothreading.t
================================================================================================
This is Rakudo Perl 6 running in valgrind, a tool for debugging and profiling programs.
Running a program in valgrind usually takes *a lot* more time than running it directly,
so please be patient.
Valgrind options can be added with MVM_VALGRIND_OPTS environment variable.

This Rakudo version is 2019.07.1.368.g.1.e.2.b.0.ec built on MoarVM version 2019.07.1.246.g.44811.ca,
running on linuxmint (18.3.Sylvia) / linux (42.16.04.1.Ubuntu.SMP.Tue.Oct.10.16.32.20.UTC.2017)
