-We should actually provide it.
+We don't really have a minimum value. We could define it to 4096 (or ~16, which
+is our actual minimum), but most applications making use of `PTHREAD_STACK_MIN`
+would just crash with such a value.
+
+The application knows way better than the OS which stack size it needs and have
+its own hint about the stack size, and thus use `PTHREAD_STACK_MIN` only as a
+minimum, not as a hint.
