I tried but ran into some further issues as some rtsan unit tests are not compatible with older glibc as `memfd_create` was not defined in glibc 2.19, it still can be invoked through syscall wrappers but that probably needs a separate patch. Therefore, I current limit the change to msan on Linux only to avoid other unwanted breakages.
