I was wondering if commit 18a4a620 might be relevant, as it touched
the management of those slots a few months ago, but then I found a
couple of matches from 2021 in my database of build farm assertion
failures:

Fairywren is a Windows + msys2 system, so it doesn't share Cygwin's
signal system, it's running the pure Windows code (though it's GCC
instead of MSVC and has a different libc, it's using our Windows
native code paths and defines WIN32).
