Meh. Well. Good to hear on the cleanup. Didn't know it used to be different :/

Re. SIGFPE, to be fair, it feels a bit like the "asynchronous vs. synchronous abort¹" thing on CPUs; synchronous aborts are reasonably doable while on asynchronous aborts you're pretty much left with torching things down far and wide.

(SIGFPE should hopefully be synchronous; it's in fact closely connected to sync/async CPU aborts...)

[¹ frequently also called exceptions, depending on the CPU architecture, but this post already uses "exception" for the language level concept]
