As supervisor actors share the same supervisor address space, they are built as relocatable binaries, leaving the choice of the final link addresses to either the system configuration utility building the system image (for the basic environment) or the Actor Manager (for the extended environment).
Care must be taken when programming supervisor actors: no memory protection is provided between supervisor actors. A badly written supervisor actor accessing addresses outside its own address space can corrupt any supervisor region and cause unexpected behavior such as a system crash or reboot.
