There's stack the CPU primitive, and there's stack the heap-allocated data structure. Goose's multiple stacks are the latter. Unrelated to OS-managed thread stacks. More like VM-managed thread stacks in Java and other bytecode languages, which also live on the heap.

Stack size is completely arbitrary, just like heap size. You have 2^64 addresses to work with.
