The dummy decides if the target is in text space or data space. If

it's in data space, there's no problem because the target can

return back to the dummy. However, if the target is in text space,

the dummy calls the secret, undocumented routine _sr4export, which

calls a function in text space and can return to any space. Instead

of including fake instructions to represent saved registers, we

know that the frame is associated with the call dummy and treat it

specially. */
