`man setrlimit`

The stack size of a thread can be set during creation with the help of
an appropriately initialized thread attribute
(pthread_attr_setstacksize).

8 MB isn't unreasonable. Most of it will be shared.

A virtual page that hasn't been used yet will have no physical page
associated with it. But how can a stack page possibly be shared and
with whom?
