Java stacks are quite small unless heavy recursion is used. This is
because the language does not use stack allocation for anything except
scalar variables -- numbers and object references.
In any case, Linux systems do not need to allocate "real" memory areas
to thread stacks -- it's all in virtual memory anyway, and physical
memory is paged as required.
