Even worse yet, macOS doesn't simply kill the process, it goes into full on kernel panic as a result of this 3.5% memory usage. I've seen that several times, presently and in the past, and have never seen it simply kill the process.

In this case a kernel panic can indeed force a full system restart instead of just terminating the process. This isn't uncommon with the Darwin kernel's handling of massive shared mappings (> tens of GB), where the upfront VM address space claim (even if physical RAM/swap is available) can trigger a panic if it fragments or overflows internal limits, rather than gracefully failing with ENOMEM. Your preallocation via fallocate rules out disk-related causes, so it's almost certainly the mmap VM bug I mentioned.
