Summary: This interceptor is useful on its own, but the main purpose of this change is to intercept libpthread initialization on linux/glibc in order to run __msan_init before any .preinit_array constructors. We used to trigger on pthread_initialize_minimal -> getrlimit(), but that call has changed to __getrlimit at some point.
