The signal trampoline on hpux actually has a name (_sigreturn), so it
fails the check in tramp_frame_sniffer ()


is this more efficient/correct? It doesn't do any code reading just
checks the pc against "_sigreturn".
Yes, definitly.  Having to do instruction examination should be 
considered a last resource.
