What issues do you perceive sharing a STATIC data area?
The issue is with a Writable not a Read-Only area. The Static area
would need to be acquired separately with each invocation and thus
would need to be accessed via a register not by relative addressing.
Otherwise different address spaces would overlay each other's data.
