I see two ways to go here:

1. Remove duplication of ICU checkout and some checkout steps (we are potentially paying 2x for LFS checkout) and keep everything in this file
2. Create a new workflow (e.g. ubuntu-memory-check.yml) and move your valgrind logic there. You will need to copy some of the triggering logic from this file.

I address both issues . PTAL
