This revision now requires changes to proceed.

I'd like to block this on `-fsanitize-memory-param-retval` (aka msan eager checks) being enabled by default. It seems pretty clear that there is a *lot* of UB due to uninitialized parameters floating around, so we should at least make sure that it is detected in default sanitizer configurations before we start exploiting it this aggressively.
