My question concerns specifically about Sun3/60 hardware:
Is there a way to restart a program at a *different* location 
than the faulting instruction at a virtual memory page fault?  
The occasion arises when the fault handler (written by me) decides 
the faulting process can in no way proceed at the faulting 
instruction, say due to a deadlock situation.  Of course, one 
alternative is to kill it.  But a more humane way is to restart it 
at a predefined save point somewhere before the faulting instruction.

Many thanks.
