I guess freebsd doesn't like small stacks... I decided to leave well enough alone. |

I guess this doesn’t change anything compared to the current situation, but should we do something like libuv/libuv@38bb0f5 (use PTHREAD_STACK_MIN only inside an #ifdef)?

Fair point. Addressed in the fix-up commit.

PTHREAD_STACK_MIN is 2 KB with musl, which is too small to safely receive signals. PTHREAD_STACK_MIN + MINSIGSTKSZ is 8 KB on arm64, which is the musl architecture with the biggest MINSIGSTKSZ so let's use that as a lower bound and let's quadruple it just in case.

PTHREAD_STACK_MIN is 2 KB with musl, which is too small to safely
receive signals. PTHREAD_STACK_MIN + MINSIGSTKSZ is 8 KB on arm64,
which is the musl architecture with the biggest MINSIGSTKSZ so let's
use that as a lower bound and let's quadruple it just in case.
This coincidentally also lets us remove a FreeBSD-specific workaround.
