Nice work!

Is there any way this can be compile-time detected? A
cursory check through the commits didn't seem to show any for me -

My racket port/fix stopped building between a few days of -CURRENT
updates - it's GC does some funky memory tricks - previously it
needed to catch SIGBUS, but now it needs to catch SEGV, so
without digging further I'm suspecting this is why - having
some kind of compile time flag might be useful in case any
other 'unusual' applications encounter similar effects.

If not - I could probably just key off of 2.13 in general,
since specific 2.13's < today will probably not be of use
to anyone other than historical interest after a time,
or maybe a revbump is in order?

- Cheers
