'RS08 Full-chip simulation of a "wait" opcode

I've seen several statements here and in the 'RS08 app. notes to the effect that a given program can't be simulated because it uses "wait."  Can anyone point me to a reference that explains this in more detail?  I've searched the forums and literature on this to no avail.
 
My own program uses RTI to wake a simulated RS08 from "wait".   The memory dump shows that the RTI interrupt is being asserted (SIP1 = $02) as expected -- but this has no effect on the PC, which remains hung at the "wait" instruction.
 
Sorry in advance for asking a question that has no doubt been raised before...
