Oops. Would be nice if print-tests.el would cover some of the more
exotic cases.
Somewhat related: I wonder if this line in print_stack_push is safe:
prstack.stack[prstack.sp++] = e;
This is not an atomic operation and prstack.sp gets updated before the
new stack slot is initialized. In theory, there is a small time window
where scan_prstack can see the new prstack.sp but not the new value for
the slot. Do we need to worry about such issues?
