PC does not have a larger address space. It simply has the option to access
other address spaces.
Collisions for PC environments cannot occur because the PC instruction must use
the token returned when you created the environment. The problem is passing
this token to programs issuing the PC instruction.
I believe IBM has some statically defined PC tokens.
