   Lately, with memray and mimalloc, we also often run into issues being reported because of spikes due to mimalloc initialization> For example, linking https://github.com/apache/arrow/issues/45236, https://github.com/apache/arrow/issues/48061 (this is similar as https://github.com/apache/arrow/issues/40301 mentioned above, but the size of the peak seems to have become larger with recent mimalloc)
